John was brilliant to work with, excellent quick service and pick up and drop off made. Would highly recommend to anyone needing IT help. My particular IT problem was quite complex but John had no problem fixing it.

Great service, issue was fixed in under 24 hours. My pc wasn't outputting anything into my monitors. When we went to John, he worked on it with effort, determination, and diligence. The process was completely stress free, and he even called us on the phone to ask questions about the situation as he was working on it. Great guy, hardworking and nice. Definitely recommend to anyone, and we will be returning if anything else occurs!

John was extremely helpful in straightening out a software attack from a hacker that corrupted my entire system. He responded the same day I contacted him and within 24 hours the problem was resolved. My computer was returned in excellent condition. The entire experience was completely stress free! His fees were very reasonable and I would recommend him to anyone. I will continue to use him for any further computer issues that may arise.

I cant express enough how wonderful of an experience we had working with John. We contacted him because we were having constant connectivity issues and my old laptop no longer was able to keep a charge. John completely fix our connectivity problems which turned out to be ineffective equipment from our service provider that we were being changed monthly for....grrrrr!!! John spent time with us and taught us about what the problem was and what type of modem and router would work best in our home. He then searched for the best deal and when it arrived he installed the new system which was no easy task. After he finished installation he stayed with us until every computer, smart phone and printer were up and running. He also recommended and taught us the best ways to safeguard ourselves during setup so that moving forward no one could access our information. Oh...and my old laptop is once again running like it did when it was new!!! I am so glad we found John. He will forever be our "computer guy". I would HIGHLY recommend him!!!!

I and my business, House of Glass, have been using Zeros Ones for over four years now. He has helped us with everything from printer setup, network setup, solid state drive installation, new custom towers, and trouble shooting. He is very knowledgeable about all hardware and software, old and new. And with as many problems we've had, I consider John a friend now. Give him a call, and I'm sure you'll be happy. Matt
