Review on Gigastone 32GB 5-Pack MLC Micro SD Card: High Endurance 4K Video Recording for Security Cam, Dash Cam, Surveillance at 95MB/s by Damon Murray

Looks very high quality. as long as they work properly. I use them in my DVR. When I play back the recordings, the images are as good as anything I've ever had. What drives me nuts is that this card and all other cards I've had don't deliver 32GB. They are all different and usually somewhere between 28GB and 29.2GB or somewhere in that range. I've never bought an SD card, regardless of manufacturer, that actually gives 32GB.
