“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 for a very reasonable price. Highly recommended.”
