I am a professional DJ and had previously had Mat upgrade my home computer. I was starting a show one night and my laptop crashed. I called Mat and he had my try several things over the phone, when that did not resolve the problem, he came immediately to my location, brought me a back-up laptop to use that night and by the time i finished my gig, he had eliminated the virus, restored all my settings and fixed the issue. He also came back to the club to return my fully fixed laptop at 1:00 am that same night. Very adept at pc repair and most importantly, he was there ready to help when I had an emergency!
