Feedback from our Customers

I've been a customer of 121 for years, and wouldn't go anywhere else. We've just purchased a new All-In-One computer and 121 have transferred all our data and files from our old computer seamlessly, and everything is working perfectly. Many thanks for your excellent and good value service.
Excellent service, had problems with a slow computer. It was suggested that rather than buy a new one a replacement hard drive was required. Was told it would take a couple of days but actually ready the same say. They also copied everything across so haven't lost any any data. Computer now good as new. Certainly recommend

We have recently used 121 for the first time. Service was fantastic getting both our all in one computer and laptop repaired within just 2 days! We will not hesitate to use them again for all our personal and business computers in the future. Would highly recommend. Thank you all at 121.

My son sent me in with the spec I needed, I showed the young lady and she knew exactly what all the jargon meant! One laptop brought home same day. Always enjoy this shop and I'm so glad it's open again, well done.
