""Go to JTG Systems." That is the first sentence that comes out of my mouth when someone in the Niagara Region asks me who to bring their computer to when they have a problem. After accidentally putting RAM in my computer the wrong way after trying to upgrade it, I went to JTG Systems and within ten minutes the problem was fixed and I was good to go. The service is incredibly fast, you can expect your unit to be fixed around a day or two on average. John is extremely knowledgeable about computers and an all around nice guy in general. If someone gave me a computer and said that everybody they went to couldn't figure it out, I would simply tell them that they haven't went to John. That's how much faith I have in him."

"Incredible service! I highly recommend JTG. My son's keyboard broke and after several phone calls to other shops and hearing ridiculous prices, I called JTG. My son's keyboard was fixed in 1/2 an hour at a awesome price. Anyone with computer problems, Bring them here. I have already been spreading the word. Thank you so much for being a reasonable, honest guy."

"Amazing prices John fixed my computer same day and did a great job would recommend"

"I had a wonderful experience. My computer (a Mac) was infected by a virus - one text to John, a prompt reply and an invitation to drop it off "anytime". When he learned that I live in Port Colborne he fixed it immediately, charged me a very fair price and had it back up and running and in my hands within an hour and a half!!! Amazing customer service!! Thanks John - you will definitely be recommended to others by me and if I am ever in need of service again I will be in touch!"

"Very knowledgeable, honest & friendly ! Tony answered any questions I had and provided very detailed answers and took the time to explain. I had brought in a desktop which I thought had a virus but did not... he took the time to tweak and repair a couple of things to make it run better. I could not have asked for better service ! While I waited !!! It was at very reasonable price . If I could rate more than 5 stars I would. I will certainly be recommening John & Tony at JTG Systems to all my friends and Family!!"

"Same day service at it's best! these are the go to guys for computer repair. fixed my computer within 2 hours of drop off! thanks again"
