Review on SanDisk 400GB SDXC Micro Ultra Memory Card and SD Adapter Bundle - Compatible with Samsung Galaxy S10, S10+, S10e Phone - Class 10 (SDSQUAR-400G-GN6MA) - Includes (1) Everything But Stromboli (TM) Combo Card Reader by Braden Bowers

I bought 2 SanDisk Micro SD memory cards (32GB and 64GB) and both soon failed. I tried them on a home security camera and two different dashcams, but they were unreliable in all cases. They start off well but stop working after a short while, but you won't know that until you watch the video. I bought a different brand DVR and it worked fine. I will spend a little more money and get a more reliable brand from now on.
