"John was great. He installed an antenna for a Helium miner for me. Very polite/friendly, on time, and communicates very well. Looking forward to working with John again in the future for my other installs! Thanks John."

"Artur and AIT correctly diagnosed a complicated problem with my home ethernet net work that has 5 eero units and CAT5 throughout the house with five switches. Outstanding professional, basically a network systems engineer. Diagnosed a loop back problem. And got my home network working at one gig speed again. I canâ t recommend him enough."

"Excellent work, very conscientious. Very reasonably priced for excellent help."

"Not only fixed my computer but provided helpful advice on a number of other issues including desirable features for a replacement computer. FOLLOW UP: I purchased a new Dell Windows 10 computer with specs recommended by Bill Marks. I also hired him to help me install it as well as simplify and move additional equipment. We did encounter a couple of issues, but Bill was able to solve them in minutes whereas it would have taken me hours. His depth of knowledge of both new and old computers is unsurpassed based on my past experience using tech support sources. I would strongly recommend using Computer Training and Support Services!!!"

"Great experience, great work."
