Happy so far, though only 475GB of usable space
Wanted to replace my 256GB system disk with something a bit larger. Cloned my drive using DiskGenius. Swapped in the 512GB disk (which actually has only 475GM of usable space on my Windows 10 PC), and everything is working great. Not sure where the other 37GB of space went, but it's a Samsung disk, so am expecting it to last at least a few years.

No problem using it (capacity upgrade)
Bought as a replacement to upgrade the original M2. No issues using it but this was done as an IT work function, and the only reliability I can speak to is I never got any negative feedback.

Lenovo IdeaPad Gaming 3
This works great in my Lenovo laptop, I'm using it to dual boot Linux and Windows (on separate drives) I only wish that it had come with a mounting screw, but there are kits for that so not to much to complain about.
