I had a 2 year old Dell that since day 1 was problematic. Even when under warranty and having Dell take a look, they couldn't figure out what was wrong. Got utterly frustrated 2 weeks ago and my father had used Nigel before and was impressed. Nigel diagnosed the problem and had the computer back to me within 6 hours. Professional, talked to me in a language I could understand and provided updates throughout the whole day. So impressed with this company. Definitely will use again as my husband had an old desktop that he was going to toss but now knows of a good professional who will have the best shot at getting it working again!
