“Took my MacBook Pro to Jumpplus only to have them tell me my computer required a $900 repair. Would not pay that so I checked around until I found JTG systems. Very honest and helpful people. Had my laptop fixed and useable within an hour. It was amazing how a $900 repair turned into a $60 one. Thanks again to John and the guys. Definately would recommend and will be going back!”
