I have bought four of these since December 8th. I installed them on Raspberry Pi 3B+ and 4s. One was delivered to DOA, one died 2/4/2020 and the other died 2/21/2020. Two of the dead were on daily duty. The one remaining block is used by an elementary school student and is not used on a daily basis. Let's see how long this lasts. I would say if you are looking for a reliable power supply and fan, you should go for RPI power supplies and a case with a fan. These are just not reliable.
