Review on Amplim 32GB Micro SD Card: 2 Pack, High Speed Memory + Adapter - Class 10 UHS-I U1 V10 TF for Nintendo Switch, GoPro, Raspberry Pi, Phone Galaxy, Camera, Tablet, PC by Lauren Parker

The cards worked fine while in my phone, but after I ejected them they became unreadable or were not recognized by any device. The first card, which I thought was a miss, happened on both cards though. Other cards from other manufacturers work fine on my device and in the adapter that came with it, so the problem seems to be that these cards don't work.
