Review on 📷 [Gigastone] Micro SD Card 32GB 10-Pack: High-Performance MicroSDHC Memory Cards for Video Cameras, Wyze Cams, Security Cameras, Roku, Full HD Video Recording - UHS-I U1 A1 Class 10, up to 90MB/s with Adapter by Robert Wood

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 dash cam 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.
