"John looked at my Mac laptop, ran a test and was able to diagnose the problem within a few minutes. He had the part I needed and he was able to fix my Mac on the spot which was amazing!"

"helped setup my universal remote control, helped with my laptop and seeing my photos from my phone and saving my important documents to the cloud. thank you."

"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."

"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."

"Extremely satisfied with the service at JTG systems! My Macbook Air would not turn on. I called and John was able to look at it that day. He fixed the problem quite quickly and now it works as good as new. Great service at an affordable price. I will definitely be back for any future computer issues!"

"John was very friendly and confident. He worked diligently to fix the problem with my Mac. He even worked on it after-hours from his house and into the evening. I really appreciated his dedication and effort. If you have any kind of computer problems, I highly recommend JTG systems for their dedication and competitive prices."

"John was very helpful he repaired my lap top added a few extras and took the time to explain how to use certain programs. I took my laptop in at 12:30 it was ready to pick up in 3 hrs... he cleaned all the malware spyware updated drivers. I have been to computer repair shops before, and i know they rip you off.

I am SO grateful. Fast, reliable, friendly service with a fair price. Thanks again John and staff!"

""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."

"I have the pleasure of not only having John as my friend but also as the only guy I will go to to have any issues with my computer fixed. Even if I just have a question or a concern John is always very professional and very respectful. I would and will always recommend JTG SYSTEMS for any of your computer need a first class company with a first class owner."

"Wonderful experience, the employees were so helpful and professional. My repairs were made extremely quick and I was able to have my device back that same day. I highly recommend JTG Systems, they are sure to not only deliver but also to impress."

"I have been long time customer at JTG Systems and I STRONGLY recommend anyone that has a computer or electronic problem (or question) to definitely bring their stuff in to get it checked out. The customer service was beyond excellent and my laptop was fixed/repaired within 24 hours of me dropping it off! The staff are friendly, and the owner John was very helpful and efficient!!! Keep it up guys!!!!!"

"From knowing just about nothing about my computer only a few basics. John has shown me all of the wonders of Google Products and my Computer is 10X faster then it was before, Free from errors and problems. My scanner works again, and he even showed me how to use my cellphone that can also do wonderful things now, Scan documents and email the whole bit. John also took the time to setup Google Docs, and a Gmail account, also Sync my Photos from my phone and computer and more.. I couldn't be happier with the service I received from JTG Systems. and I drove from Hamilton a 30 Minute drive.. Was definitely worth it. This guy knows his stuff inside and out and I would recommend to family friends and others. go to JTG Systems and you will be happy you did."
