I recently purchased 64GB of DDR4 RAM and a 2TB SSD drive from Mr Memory, and I couldn’t be more pleased with the experience. From start to finish, the service was outstanding — a big thanks to Kerry and Kevin, who made the whole process smooth and enjoyable.
The prices were very reasonable, especially considering the high quality of the products. Both the RAM and SSD are performing flawlessly, giving my system a noticeable boost in speed and efficiency.
Special thanks to Kevin for his trust and patience, which really helped me get up and running very quickly with the new hardware.
Overall, I highly recommend Mr Memory for anyone looking for reliable, affordable, and high-quality computer components backed by excellent customer service.

Good at selling good memory at good prices.
They sell memory. The memory is good. The memory is cheap. The memory arrives exactly as described, quickly, and safely. If there are problems with your payment, they email you and fix them, and they put their number on the email so you can call if you want.
