"Mike was able to get the upgrade on to my computer and he also was able to determine that the system was grossly inadequate for what I wanted to do. He recommended what I should look for when I purchase a new one and when I do make a purchase I will be calling on him to get my system up to speed. I was most impressed with Mike’s professionalism and knowledge and I would definitely recommend him for any computer issues."

"They were helpful. Apparently my computer was working very slowly and after they went through their diagnostics, I think it was a remote, I think it worked a little better but it didn't quite work as well as I was hoping. I'm not going to say it's their fault or something else is going on in the computer. I don't use that computer much anymore but I don't necessarily blame them or if there are some more issues with our computer. They did tell me that what they can do remotely is limited and they have to take it in somewhere to get more done. They were pretty upfront about that. The price was fair. They responded within that day. The end result didn't meet my needs."

"He took a generous amount of time until it was completed.  Friendly and professional.  <br /> It's nice to get this resolved for a low amount of money without taking the computer out of my home and/or not being able to use it for a few days.  Convenient way to receive computer repair services. <br />"

"The repairs was done wonderfully, i had the service through phone & was serviced on time & they were great & repaired my computer perfectly. I originally got his name thru Angie's List."

"Do you have a talented, experienced, responsive Technical Support group at your disposal? No? Neither do I, but I don't care anymore because I have Mark. Running Windows XP on my vintage computer was getting in my way, so I called Mark to help me upgrade to a newer computer given to me by a friend. I read his wonderful reviews, but Mark still exceeded all my expectations. We needed to set up the new computer so it could communicate with my wireless modem, install new versions of software packages from my old system, and port over all my old files. I don't do change well, so I wanted everything on the new computer to look as much as possible like what I was accustomed to seeing on my old system. Mark even had a way for Windows 8.1 to look like the Windows XP formats I was used to! Mark arrived on time and went promptly to work. I was impressed with how experienced he was and how smoothly he went from one step to the next. He didn't dawdle, get distracted, or become puzzled. Tasks that were complex and overwhelming to me were very familiar to him, and he accomplished them with ease. He knew what questions to ask me to see if there would be issues down the road. For instance, when the new computer was up and running, he checked the download speed and discovered that it was really poor. He called AT&T for me (yes, he even speaks AT&T!) and we found out that I could get much faster speed AND save money with a new AT&T Uverse package. I asked Mark to come back and install the new modem that came with the new package, which he did and checked out everything to make sure all aspects of the new system were functioning properly. We had a problem getting my phones to work with the new Uverse system, but Mark applied his expertise and got that to work as well. Mark is patient and understanding with people who are not technologically savvy. He communicates very clearly. He asked several times if I had any questions, to make sure I had the answers I needed to be comfortable with the solutions he provided. He even made follow-up phone calls to check in and make sure everything was running properly. For someone like me, who loves my computer but is helpless if anything goes wrong, that level of care means a lot! I would recommend Mark's services to anyone with computer issues. I don't know if Mark is a Wizard, or a Cyber-Jedi, or what, but I don't care as long as I know he's there to take care of my computer. Thanks, Mark!"
