I installed it on a Lenovo ThinkCentre tiny PC running proxmox with various VMs 24/7 for several months without any issues. Satisfactory speed.

Simple and functional, you can't expect anything less from crucial. Make sure you have correctly chosen the RAM model (DDR4) and speed.

I upgraded my laptop, Inspiron 15 7000, which already had 16GB DDR4 2400 RAM on its own. I added this one as a second one and it was perfectly compatible.

Unfortunately, this specific memory had several failures with my computer (acer aspire 5 a517-51g-58zh), with the most significant being crashes in Firefox or Opera.
I did not notice faster read or write speeds during file transfers.
The rendering time did not improve in video creation.
I did not notice faster performance when using multiple windows on the desktop.
Simply put, the 10 seconds it took for the laptop to start up became 5 seconds.

I used it to upgrade my mother's laptop for her work. The laptop is the HP Pavilion 14 ce0003 and following the HP manual's instructions for service & upgrades, replacing the RAM was very easy. The laptop recognized the RAM on the first startup without any issues.

I bought it and replaced the memory in a new laptop purchased for distance learning, and it works flawlessly with plug and play connection

Fast good cheap and huge :)
Great value for money, excellent.

Worked perfectly on Accer Aspire A515-51 N17C4
