These guys are great!
I had a problem with my computer and frankly I know jack squad about fixing such problems so I called my friend and asked him for advice. He recommended me Geeks2U and said they work really fast and efficient. That same day I called them and a really nice and friendly guy (don't remember his name) came over after half an hour. He didn't just fix my computer, but also explained what exactly he was doing and why. I was even surprised I understood everything he said and he didn't mind my endless questions.
All in all I totally recommend this company, even though they are a bit pricey for my standards.
