Works great.
I have a dell inspiron laptop and checked their website for the type of memory. I went to Crucial's website to check their computer finder-memory match app. They both agreed. Since then, I have actually read up on my memory and now am 100% confident I purchased the correct one. I bought from calvinNhobbs. Amazon was out and not expecting inventory for a while. It arrived fast and in good shape. I put it in (I already had 1 stick originally installed). I just matched the size (mine was 8GB) and other parameters. The win10 inspiron computer found it and booted up fine - great stuff! CPU-Z did not distinguish between the modules when exploring the memory which means that the match is really good. One thing to note, is was 2666 MHz memory, matched to the original. Due to the way computers are made, it only runs at 2400 which is as it should be. This can be confusing but it is correct. Read up on it.

Works flawlessly as upgrade from 4GB to 8GB.
Purchased two 8GB SODIMM memory modules for HP 15 Laptop based on recommendations from both HP and Crucial that a memory upgrade from 4GB to 16GB was available for this model. On opening the case I found only one memory socket had been soldered to the motherboard. Returned the second memory module for refund, but had to pay ~$3.50 postage, otherwise I'd have given 5 stars for "Value for money". The upgrade from 4GB to 8GB solved the problem of slow response time from the computer that plagued it since it was new. SystemInfo.exe reports only 8024MB "Total Physical Memory", instead of the 8192MB expected, otherwise I'd give 5 stars for overall rating.

Works Like a Charm, Easy Install
I am very please with this ram stick. I just popped it in to my empty slot in my MSI GF65 thin and it worked right away upon rebooting. Now I can run some more resources heavy games :-). 10/10 would recommend

Low cost upgrade to keep your laptop modern
My struggling laggy laptop is now back to zipping around again. Quick, easy upgrade. Works great despite being a used item, computer recognized the memory upgrade, computer is stable with no weird crashes after the upgrade, and all is good.

Perfect add-on for my Synology DS220+
Installed this 8GB RAM in my DS220+ and the DSM immediately recognised the memory (to a total of 10 GB). Perfect alternative if you intend to increase your Synology RAM as the price is so much cheaper than the official memory chips. Disclaimer: I have only used it on DS220+ and it works. You may wish to experiment it on other Synology models.

Works great with my Synology NAS DS720+ !
After struggling a bit to find a suitable memory for my Synology NAS DS720+ someone recommended me to get this memory. Was very simple to install and my NAS identified the memory straight aways, booted up without issues and has been working well with the latest DSM 7.X versions. Considering that the official Synology Memory is quite expensive and hard to get, this one is a steal and performs great. Highly recommended. June 2022

Good Product
I bought this item on a plan to add it to the existing 4gb ram on my HP Laptop and that's what I did. surprisingly, the Laptop became even slower than it was before. I had a doubt and removed the old 4gb ram and ran the system with only 8GB and it blew me away. Works very well and faster. I never understood why the other 4gb didn't work together with the new one. If anyone knows, please do comment.

Funcionando sin problema en iMac 2019
Buen producto a un precio muy razonable (sobre todo si lo comparamos con lo que cobran en Aple o en sus distribuidores). La instalación el los iMacs 27 de 2019 es muy fácil.
