Review on KEXIN 64GB Micro SD Card Class 10, U3, MicroSDXC UHS-I C10 - High Speed Memory Card (3 Pack) by Mike Mitchell

We bought these to use with our home video surveillance system (Yi brand, only 5 cameras were built over time). After over a year of working and sometimes not working these cards, we decided to throw them in the trash. Please note that we use SanDisk cards in 3 of our 5 cameras and Kexin cards in 2 other cameras. SanDisk cards have NEVER failed while Kexin cards have failed SO MANY times. If you want consistent reliability, spend a little more for a more reliable card.
