"Excellent experience working with John. I called him on a Saturday expecting to have to leave a message and thought I'd have to drop my MacBook off the next week. Instead, he answered the phone and told me to bring it in right away. Dropped it off a few minutes later and John said he would get it done by the end of the day! Apple could not help me with their own machine, but John did, and he did it fast! I had been waiting for over a month for Apple. My MacBook has the weird "C" style USB ports, and I forgot to bring the adapter. John even offered to come and get it from my house in order to get the job done! My advice? Support your local businesses, especially the ones that provide a high level of customer care. I hope to never have computer problems ever again, so I'll never have to go back, but who are we kidding? It's going to happen, and when it does, I know where I'm taking my computer! John goes above and beyond to serve his customers. Highly recommend JTG Systems!"

"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"

"all in one works 5X faster thanks, also helped me get rid of malware infecting the computer and other security problems computer is way faster. and they fixed it the same day like the ad said. I dropped it off at noon and was called before 5 to pickup! wow."

"Computer was serviced the very same day and its 10X faster, JTG Systems is Truly Niagara's best computer repair."

"Still great service!! If you don't know anything about what's going wrong with your computer/laptop - don't worry...

My PC crashed on Thanksgiving weekend - JTG Systems came to my rescue and i was up and running within an hour. Replaced my hard drive and not only is everything good my laptop performance is way faster than before! JTG will take the time to go over what you need and provide you with the best solutions and they stand behind their service!!"

"My son John Gallie runs a professional computer company JTG Systems! He treats everyone with respect and does great work. He has been self employed for about 10 years. Great Job!!"

"JTG Systems is truely the best techs in niagara, they are always there when i need them and on top of that i get same day service. thanks again. niagara computer repair experts at their best."

"I called John and had my computer fixed that day. Within 5 minutes he had it up and running. I previously took it to another place and they were unable to fix it or retrieve the data off of it. I am so thankful I was referred to John! I would never take my computer to anyone else."

"speed up my computer, tested everything out. Installed an Ad-blocker so i don't get any more ads, everything works great and fast."

"Always have had the best service with John no else works on any of my computers"

"Got a laptop fixed there.Hard drive was replaced and laptop was cleaned out. Quick and easy service. Very friendly in store and on the phone when I call and asked for a quote. Definitely will come back!"

"John is really friendly and very knowledgeable when it comes to computers. My gaming PC wasn't working properly he fixed it within 2 days. He's very nice and I loved the service i received. I would recommend to all my friends and family. Only thing I could say that needed improvement was communication between him and customers but that's just me nitpicking."

"John and Tony know their stuff quite well. They offered professional service for a really low price. They knew exactly what the problem was and fixed my laptop to make it brand new again. I'll be going back to them for future business."

"if i could give more than 5 stars i would!! John was a pleasure to work with in fixing my computer, negotiated a good price for the fix with the proper components i needed and all of it was done in less than an hour in the shop. honestly cant say enough about how convenient and easy it was as well as was just nice to have some good conversation in regards to information i needed to do with building a computer. would recommend to anyone needing to get their computers or laptops fixed or anyone looking to get a refurbished piece of equipment!!"

"answered my call and fixed my computer the same day. thank you."

"JTG Systems is a life saver. John is confident and a quick problem solver about what he needs to do in order to help me as a client. Oh, and did I say quick? Today, within minutes he fixed my laptop, which for everyone else was a mystery to solve. He's a great person to have on any small business team that's struggling with daily computer challenges."

"These guys were great very professional and helped me out even after hours. My laptop runs super fast now. Awesome job and very reasonably priced I'd recommend these guys to everyone needing tech help."

"Thank you, came to my home setup my email and helped speedup the computer works nice and fast with no more issues! I was recommended to JTG Systems for Onsite computer repair by my Daughter, - thank you to her for the referral."

"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!"

"Very impressed with how quickly our computer was repaired, price was very reasonable as well,"

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

"I have a MacBook Air that is only a year old and used for Word or regular websites. My charging port stopped working so I went to BestBuy, they quoted me $300-$900 to fix or backup my information for $100+tax. I walked out feeling stuck and hopeless. I decided to call someone who specializes in Mac and isn't "corporate".Called JTG systems. Came in the next day, charge port was slightly moved and he put it back in place. Was very understanding and informative! 10 seconds and my laptop was working again! He then added virus protection programs to remove a current virus causing popups and also showed me tricks I didn't know about my Mac. Ten out of ten would recommend. Forever customer now."

"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 have always had success with John! Thank You for Speeding up my laptop, runs better than when I got it out of the box! Super FAST!! Thanks again."
