"John was recommended to me by my sister. She told me that he would be able to fix our computer and speed up our Mac so we could optimize its use for another several years. We have a 2009 Mac Book Pro. John took a look at it and immediately came up with a recommendation. John also understood that it would be difficult to be without our computer for a number of days so he had it back to us within 24 hours. John is extremely professional, knowledgeable and accessible. Also, his prices were very reasonable and affordable. All of which, I really appreciated it. I highly recommend JTG computers!"

"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!"

"John performed onsite computer repair, he came within an hour of being called, showed up on time, fixed my problems and then some. Thank you."

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

"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"."

"Employees were kind, and efficient. Did more than asked. Reasonable price as well. Definitely recommend this for anyone needing help with their computers."

"John and his team are Amazing!! JTG Systems came to our clinic and put in a wifi extender and our practitioners and patients did not have to miss a beat. Their service was extremely professional and efficient. They truly care about the quality of their work and they will be taking care of all our future computer needs. I highly recommend them!"

"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 is very knowledgeable and is incredibly helpful. I can highly recommend him. Please use him for all your computer needs!!!"

"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"

"JTG Systems has been doing my computer maintenance and repair for approximately 5 years now. I'm on the road continuously and their quick "walk-in" service has been a real asset. They always do what they say that they are going to do and I've never felt let down or overcharged during that time. Jim Cowan Classic Auto Appraisals"

"Excellent, efficient, professional service. I walked in, the problem with my laptop was determined within seconds, repaired while I waited. I would not go anywhere else. Such a pleasant surprise."

"Brought my laptop in a few days ago due to a overheating problem and they cleaned it up for me, it seems to be working great now with no issues. Thank you !"

"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"

"I had a very pleasant experience with John at JTG. My pc was having issues for a while and I was expecting to have to wipe everything, when I brought it in I wasn't entirely sure what I was able to do, but John had me fixed up and ready to go for a fair price in under an hour. I highly recommend this repair service."

"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."

"Took two laptops in for different issues. Computer one was completed and working perfectly on return. Computer two took another trip but they were very professional and second trip was free of charge and they helped find additional solutions. Thanks very much."

"John was quick to help and locate my 50,000 plus pictures that were on an old hard drive in a Memory Manager Program and transfer them ALL to my new(er) computer into the new version of (M.M.) called Historian. I am SO grateful. Fast, reliable, friendly service with a fair price. Thanks again John and staff!"

"Truly superior to every other repair store I've tried. Fast service. Very friendly people. This is my go to for computer repair. 10/10 would go to JTG again."
