## Customer Reviews

### ⭐⭐⭐⭐⭐ Reasonably priced
*by  ***B on June 13, 2021*

These where a match for the mobo I bought recently and they haven't given me any problems yet. Simple installation, just gently push them into the correct slots and your done. I believe I bought these while they were on sale so for the price it was a great find. It's only been a couple weeks of use so I will update if there are any negative changes. At this time I would recommend these to anyone who's mobo is compatible with them.

### ⭐⭐⭐⭐⭐ exactly what I wanted and worked fine.
*by G***R on November 10, 2022*

USPS shipping was slow. Product is good.

### ⭐ I purchased the 8GB kit, but one of the rams didn’t work..
*by F***L on February 19, 2021*

My computer has a pre-installed 4GB RAM. When I replaced it with that pair and pressed the power button, the computer made a noisy beeping sound and didn’t start. At first, I thought one of the slots was not working. I decided to do an experiment by installing the old ram again with each ram that came in the kit separately. It turned out that the beeping sound would start when I installed the old ram with one of the new rams but not with the other. Unfortunately, The return window on Amazon had closed before I found out about that issue.
