Customer Testimonials

I had a great experience with Computer Repair that the service was fast, effective and professional. only one thing. being a luddite i would have liked a little more explanation of what was wrong with my computer. apart from that it was great!


The service was excellent and extremely good value for money. I thought that my laptop was pretty much beyond repair, but it came back better than ever. (Plus cleaner than it was when I got it!) Everyone I spoke to or emailed during the short time it was being repaired were helpful and professional. I would definitely use this service again, or recommend it to others. Thanks very much.
