Review on Kuesuny 4GB Kit (2X2GB) DDR2 800MHz DIMM PC2-6300 PC2-6400 1 by Don Taniguchi

I received and installed them on March 6, 2021. It took about five minutes to install, but should be quicker for most people (I have it on a network rack shelf in a somewhat awkward configuration). Use this for a pfsense router/firewall for my home network. This means that the machine is always on. 13 days of continuous work with no problems. So far so good, but I'll update in a few weeks or so. Update: Almost 5 months later they are running almost continuously (less than 3 minutes of downtime) with no issues. Definitely recommend and buy again.
