Review on TopeSel 32GB Micro SD Card 2 Pack - High Speed Memory Cards | UHS-I TF Card Class 10 for Camera, Drone, Dash Cam | 2-Pack U1 32GB by Gary Stringfield

I was skeptical because of the low price but works well so far (SDHC UHS-I card and it delivers this speed). I've used it in a security camera (720p) but I've also tried it with a Raspberry Pi and it works great. Don't expect amazing speeds. If you store important data, I would suggest making regular backups to be on the safe side.
