Very happy customer!

I found Mr Memory via a search when I could not source the RAM required from my usual provider.
I could not have been happier - the website is excellent and it was easy to find what I wanted. It arrived rapidly and worked perfectly. My ailing iMac is now super fast again. Thanks Mr Memory!

Absolutely fantastic

Absolutely fantastic, Ordered RAM for a Dell Latitude 7280 as I was struggling to find definitive answers on what was compatible and had seen Mr Memory had a guarantee on compatibility. The first stick that arrived worked but was not compatible and returning it was so easy and the form had space to fully explain the issue, as well as what RAM i already had - Second stick arrived and worked perfectly.

Will definetly use again, fantastic service and reasonable pricing.
