Review on 📷 [Gigastone] 32GB Micro SD Card 50-Pack, Camera Plus, MicroSDHC Memory Card for Video Camera, Wyze Cam, Security Camera, Roku, HD Video Recording, UHS-I U1 A1 Class 10, up to 90MB/s, with Adapter by Brandon Addison

If you need it for a smart device or in my case a DVR. Save your money, it caused a freeze, hard reset and finally my dashcam stopped working. Recommend sandisk with ultra plus 100mb per second. It's terrible, no deal. Revain does not return this product either, only exchanges it. The seller can be reached via his website. Don't expect a return. I'm hoping to give it to someone who has an older and slower device or it will have to be thrown away.
