Working flawlessly
It took a little trick to crack open my laptop, but installing the Crucial 16GB, 260-pin SODIMM was super easy. After the installation, my laptop became much more powerful. Good quality and compatibility.

Great company, great product, great results
Popped right in and worked exactly as needed and described. No laptop should ever be sold with 4GB of Ram - this made that laptop zip right along - Great product

Works with Synology DS423+
I bought this to improve upon the laughable 2gb of ram built into the synology DS423+ and it seems to be working great! I had to look at the instructions on how to insert it because I've never used a NAS or this type of ram stick but it was super easy once I looked it up. I can't speak to performance since I didn't use the NAS before installing this, but it shows up and hasn't had any issues in the month or so I've been using it. Would definitely recommend for the DS423+ for a fraction of the price of the Synology branded ram.

Works as expected with Synology NAS
Purchased for use in a Synology DS920+ per internet guides stating this particular sku was compatible. Installation was quick and easy and the NAS booted up with no problems and now shows 20GB system RAM.

Product quality
I've upgraded my Lenovo Ideapad Core I3 laptop from 8GB to 16GB RAM upon the arrival of it on Sat. It works perfectly now. Used to be sooo slow. Many thanks! The only reason I rated it 4 rather than 5 was that a 8GB ram was mistakenly shipped, but the seller acted so quickly to send the correct. I know its a forgiven error that happens
