"I had an issue with my iMac a while back and contacted John. It was done within 48 hours. He is fast and he will help you as much as he can. He will diagnose and explain the issue with your device and give you options where possible. He is an honest and straight up guy. Good job guys and thank you!"

"John Gallie has assisted me with computer problems a few times, from simple to complex. Even the simple is complex for me. For him, maybe 5 seconds to diagnose and even less time to fix. The complex paralyzes me. To John it takes a few minutes to fix. As always his prices are very reasonable. He knows how to take care of his customers, especially those like me: absolute techno-flops."

"JTG systems, John Gallie is the most reliable honest computer guy you can get to fix your laptop or desktop! Who can beat same-day computer repair? And if you're not sure if you can trust leaving your personal information in someone else's hands you can 100% trust John! He has a police clearance, took police foundations in college, served in the military, and volunteers for crime stoppers. I highly highly recommend him! Two thumbs up! :-)"

"Brought in my 9 year year old, slow iMac to discuss whether to upgrade and tune it up, or replace it. John and his friendly team took a quick look and recommended some clean up, additional RAM and to consider replacing the hard drive. It’s now running like a new desktop, but at a fraction of the the cost of going new. Highly recommended."

"Although my laptop is now an expensive paperweight, I am super thankful for the great service I received from JTG. They were honest about the cost of fixing VS getting a new one and didn't even charge me. Highly recommend"

"helped setup my universal remote control, helped with my laptop and seeing my photos from my phone and saving my important documents to the cloud. thank you."

"John is incredible. Helped me figure out what had gone wrong with my MacBook without charging for Diagnostics like they do at Jumpstart. If you are a student in Niagara with computer issues it is 100% worth it to take it to John. Fast, reliable and most importantly helpful and cost effective! Thanks again John"

"John was great! He even waited around after he closed for me to pick my computer up the same day."

"JTG Systems (John) helps me with all of computer stuff and my personal goals including getting my business up and running, I always wanted to be a personal trainer, without johns help i am lost and wouldn't know what to do. I really appreciate all of your help through out the years. Thanks again."

"John and his team fixed our desktop gaming computer in an afternoon. Knowledgeable, approachable and all around a positive experience as always!"

"Had a large external hard drive that crashed and I thought I had lost some important photo files that I had not had a chance to back up. John was able to access and retrieve my data. I was impressed by the service and dedication to my situation and will not hesitate to return in the future, I highly recommend this company....Harold Hutchings-HJH Photography."

"The service was great! My external hard drive broke and I lost almost all my files. It was an apple product and the apple store told me it couldn't be fixed. I brought it to JTG and all my data was recovered in about a day! It was very efficient and resonably priced as well. I would reccomend JTG to anyone who needs data or hardware help."

"John has been looking after my MacBook Pro computers for many years. His commitment to customer service is exceptional! He is always thinking about how he can save my business money with my Macbook Pros. Apple product servicing can be very expense and time consuming to fix at other repair shops but John always gives me great advice and prompt service."

"I called JTG Systems for repair on my Imac, it was shutting off..constantly.. and filled with malware, I dropped it off the same day with no appointment after I called, They took it in and worked on it right away until finished. they even updated my OS at no extra charge. These guys are great! I would highly recommend to friends and family. thanks JTG Systems for your hard work on our family computer."

"JTG diagnosed the problem, was professional and courteous and gave my mom a seniors discount. Very happy with the quick service!"

"This Google Review is made possible with my new fancy Dell Tough book. The refurbish laptops being sold by JTG are fully functional, B grade units with years and years of potential. Thanks to JTG for dealing with me i can be a difficult a customer but they made the transaction and dealings very pleasant."

"I had a great experience with John, he was very professional, patient, knowledgeable, trustworthy. He kept his word about keeping to the agreed upon estimate even though he had to do an additional hour on another day of work to get my iphone working. I would definitely recommend this service to others. He keeps costs down by working in a smallish/humble space, which I also appreciate."

"Best service around ! Great to deal with and most fare price ive had for repairs around !! 10stars dnt get fooled by these other companies out there , john is the real deal !"

"Super casual and friendly, definitely recommend for those who need a quick fix for cheap! Thanks again."

"I thought my Mac was past it's lifetime as one day it made such a loud noise and then would not turn on. Oh I tried with tips and tricks but no luck. Then to my luck I found JTG systems. I did not even call just showed up and Anthony greeted me and accepted challenge. His patience and experience was amazing. He fixed my problem and even was willing to help me upgrade. I have NEVER had such an experience as positive as I did today with JTG SERVICES....Anthony you rock !!!!! I will recommend this company to everyone who has computer issues.....especially your Mac. Cheers Carol"

"John is one with the computer. Most guys need to Google the fix. John has it all in his head."

"just amazing....great prices ..friendly service... same day service (screen replacement and software update).. not to mention my macbook is an older model and I hear most places wont work on my device anymore even tho it runs great....sooo truly grateful to have been referred here! will be sending my friends in too!"

"Brought in my desktop today after lunch. It was unresponsive and would not boot up. John and his friendly team were able to diagnose and repair the same day! Reasonable rates and very quick service."

"Took in an HP laptop with a cracked touch screen and they had it diagnosed and in working condition within an hour and a half! Way better price than any big tech company and honest advice! Going back here next time I need laptop help"

"Very quick service, really enjoyed the friendly atmosphere and the results were good! Still cant play sims though, so may be time to upgrade 😂 will go back for more repairs or questions in the future."

"John did an excellent job on my computer. I was so worried that I had lost all my files but he brought them back and installed a new hard drive. Thank you, Johanna"

"Thank you so much John! Quick, friendly and expert advice. Diagnosed and fixed my Mac issue within hours. Very much appreciated and recommended!"

"We're using JTG Systems to support our locations in the Niagara Region and John has been quick and very professional visiting the sites and resolving their issues. It's great to have him taking care of those systems for us here at Intrigue."

"Got my sons gaming working perfectly, very friendly, very knowledgeable, and Most importantly he is very honest and reasonably priced. Will use his services again If needed."

"I was only in town for a night and wasn't able to get my MacBook serviced. But I was contacted via text message and they explained that I could easily purchase a battery off amazon and use YouTube videos to install it myself. I really appreciate the honesty and customer commitment."

"Very professional, quick and reasonable for pricing. We were referred to John's business from our own Royal LePage IT professional for a service that would have cost $300 by Dell Computers (for a battery replacement/install) and we were charged a very reasonable $65. We highly recommend JTG Systems. John and Cindy Raskob, Royal Lepage NRC Realty."

"Extremely happy with the work John did to get my computer running the way it should. He is personable and was able to quickly diagnose the issue and remove the gremlins. I will recommend you to all my friends!"

"**************HIGHLY RECOMMENDED************* I brought in my old Mac to APPLE STORE and they won’t change the battery cuz it’s “too old.” Thank God I googled “computer repair in niagara” and JTG staff replied within minutes, directed me to the Amazon link to order the battery and bring it to them to install. (VERY HELPFUL, thank you) When I brought in the battery and the Mac, the staff were all friendly, welcoming and very professional. The location is easy to find with free parking and close to Tim Hortons and Dairy Queen. The battery literally was installed in less than 5 minutes and they took the time to explain recalibration with me. (I appreciate that, thank you.) The staff mentioned a hard drive update would make the Mac go so much faster. It was only $100 and included an external hard drive. This installation only took an hour and it was no problem waiting since the mall is so close. The staff are kind and extremely efficient. I highly recommend everyone to bring their PC, MAC, and other devices into JTG. You guys are family now. Thank you for taking care of everything. It really took a weight off me. Sincerely, Laine LePoidvin"

"I reached out to John after he was recommended to me from someone on a Niagara Advice Page. From the initial contact I felt I was in the best of hands. John was able to assist with a recovery of lost files & pictures after my Macbook decided to do a software update. Throughout the whole process, John was available through text message to alleviate all my stresses with the thoughts of losing years of memories. Would not go anywhere else from here on out and will always be referring him to friends and colleagues. KUDOS TO YOU & YOUR TEAM JOHN!!!"

"Computer was slow and wouldn't load properly. JTG Systems had it diagnosed and up and running in about 30 minutes. Full diagnostic followed and haven't had a problem since."

"Took my slow older unit into John to have him take a peak at it. Within an hour it was back to optimal speeds, asked permission to exchange parts for better ones with minimal cost, updated windows and all drivers for fast and effective processing. Would recommend over any other shop in the area."

"I recently got my laptop screen replaced and the service was professional, quick (two day turnaround) and most importantly it was inexpensive. The service was highly recommended and my experience was great."

"I HIGHLY recommend JTG Systems! John was extremely helpful in assuring me that my old Mac was an affordable, fairly simple fix. When another local computer repair business told me it was a lost cause, I almost gave up on it. He replaced my hard drive, added more RAM, updated it and explained everything he was doing in a way that I (a not so tech-savvy person) could understand. In just a couple hours, my computer was ready to be picked up and he even lent me a cable to connect my old hard drive to the computer, and move over old files. I'll definitely be calling JTG for any of my computer needs from now on. Thanks again, John !"

"I was very impressed with the honest feedback I received about my laptop repair. I was told it would cost over $200 and I'd be back in 3 months with the same problem. I applaud JTG Systems for their integrity and will happily recommend them."

"I had recently lost ALL of the documents and pictures on my laptop (years worth of important stuff!). I had called around to a lot of different places where I was told to bring in my computer for a high price to see if they "could" recover it. When I called JTG Systems I was overwhelmed by the friendly and helpful voice on the other end of the phone. He took the time to talk & listened to my issues with the computer and gave me an excellent price. I brought in my laptop plus another one to get cleaned up and was SO HAPPY with the service and time this was done in! All of my pictures and documents were restored & transfered to a safer place PLUS both computers were cleaned up .... all in two days!!! FASTEST and BEST service I have yet to experience ... & I will FOR SURE bring my computers here from now on and recommend them to anyone I talk too! So awesome!!!"

"When John says he's open 24 hours, he's not kidding. He was willing to work around my schedule in order to get my PC back to me as quickly as possible. Couldn't be happier with the quality of the work. He repaired, optimized and cleaned my machine, all for a very reasonable price. Highly recommended."

"John at JTG Computers has been very helpful in repairing/updating both my Microsoft and Apple computers. His service was prompt and efficient. He has also given my advice via text or telephone. I would recommend this company for assistance with your computer needs."

"Just another happy customer here with a repaired Macbook. John has done some Christmas miracles on my laptop, and everything is back on track now. He is indeed the best in the business considering the time, money and the quality of repairs which costs the fraction of what it would've cost if I went with Apple "geniuses"."

"John looked at my Mac laptop, ran a test and was able to diagnose the problem within a few minutes. He had the part I needed and he was able to fix my Mac on the spot which was amazing!"

"Worked on it right away, and was easy to contact. Unclogged my headphone jack. Something was stuck in there and near impossible to get out, but he solved it. Thanks for the good work!"

"When it comes to computer problems we all panic fearing the worst. Always fearful of lost data and complete system reinstalls. I walked into JTG one day with 2 laptops with software issues. A few hours later I walked out with 2 repaired laptops. Very reasonably priced and great fast service. I will recommend to others needing computer repairs. Thanks fellas."

"Great experience. John is really personable and helpful. He got back all of my data that I thought was completely lost. I definitely will send more work his way. Trustworthy, straightforward and honest."

"I brought my Macbook in for repair, unsure if it could be fixed. JTG Systems worked hard to diagnose and solve the issues. Thank you!"

"JTG Systems is the best place to bring your computer or electronic device for repair in the Niagara Region. The staff is extremely knowledgeable, the work is efficient, and the pricing has me returning. I've had them retrieve lost data off my cell phone, give my old laptop a tune up (saving me from having to buy a new one), and even had them put together an entirely new gaming tower for me. Each visit has me coming back the next time!"

"I thought our files on our external harddrive were lost forever! Tried a few places with no luck, but JTG was friendly, quick, knowledgable, honest and fixed my issue on the spot; AND for way less $ I though I would have to spend!!! Definitely recommend them for any of your hardrive/computer needs!"

"Lost the use of our laptop found a professional knowledgeable technician. Moved up to #1 on our favorites. John went above and beyond, thank you."

"Good, honest work! I have had nothing but GREAT service from JTG - almost everything I have brought to John has been fixed no problem. The things that couldn't be fixed, there was no charge. The service is very quick and professional. I have recommended JTG to friends and family, who have also been very impressed with the service and professionalism. I will continue to use JTG and have no problem recommending it to everyone. Keep up the great work John!!"

"In a rush I was trying to find a phone repair place around 9pm. Everything was closed and I was lucky enough to run into one of the workers outside the store. They had closed an hour prior but was still willing to fix my phone the same night. The guys that were there was super friendly and easy to talk to. Under 40 minutes later my phone was fixed. I was so happy I almost cried.It was absolutely amazing service. If you need anything fixed go to these guys. If those guys are reading this: name it Rocket :)"

"We've been using JTG for several years now and they have never let us down. From computer repair, mobile cracked screens and even recovering lost data. The owner and his team are talented and fast. Highly recommend."

"I just brought my laptop in for service, I needed the viruses removed and windows installed. John was extremely helpful and knowledgeable. The service I received was prompt and the cost was very reasonable. I would recommend JTG Systems to anyone looking for service!!!"

"Took my MacBook Pro to fix the audio jack. They weren't able to fix it without a new part. I did not wish to purchase the new part so they put it back together for me at no cost even though I expected to pay for the labour spent taking it apart. Thats stand up customer service. I will recommend to all my friends and family."

"From knowing just about nothing about my computer only a few basics. John has shown me all of the wonders of Google Products and my Computer is 10X faster then it was before, Free from errors and problems. My scanner works again, and he even showed me how to use my cellphone that can also do wonderful things now, Scan documents and email the whole bit. John also took the time to setup Google Docs, and a Gmail account, also Sync my Photos from my phone and computer and more.. I couldn't be happier with the service I received from JTG Systems. and I drove from Hamilton a 30 Minute drive.. Was definitely worth it. This guy knows his stuff inside and out and I would recommend to family friends and others. go to JTG Systems and you will be happy you did."

"Jon has helped me out more today than any other company has in the past 2 weeks after my laptop completely gave out. Most places I went to gave me no information and simply just wanted my money. Jon seems like he cares! He's easy to communicate to and seems 100 percent genuine. The type of person who will go out of their way to get you what you need. I'd suggest going to JTG computer repair if you want someone who wants to help and who can help!"

"John fixed my computer in a flash really good price awesome costumer service skilles answered all my questions were answered I recommend john to anyon with computer problems"

"Amazing service !! John is such a nice guy and very honest and will do his possible to repair your computer at the lowest price and quickest time he can. I’m really happy I found him ... I’ll never go anywhere else!"

"Really good experience, took a look at it right there and then and was able to fix the problem without charging diagnostic fees and waiting a day just to see what was going on. Highly recommended"
