Review on 💾 Gigastone Micro SD Card 32GB 5-Pack: Camera Plus, Memory Card for Video Camera, Wyze Cam, Security Camera, Roku - Full HD Video, UHS-I U1 A1 Class 10, up to 90MB/s with Adapter by Dennis Reed

I ordered them as they turned out to be very profitable (5x 64G), but when I tried to copy the files to the first one it didn't stop reporting how rights are protected. I kept trying to use multiple computers/laptops/devices and even different adapters but I was never able to write data to it. I finally gave up and tried the next one in the pack with exactly the same experience. The next one I tried worked fine right away so I tested the last two and only one worked, with a failure rate of 3 out of 5. I requested a replacement from Revain who arrived the next day and tested all 5 immediately found, that only one card failed due to write protection. Still 20% initial bounce rate, but I keep one of the original working cards and send Revain 4 bad cards back with a good one. If one of them fails in the next few weeks, I'll spend more on Samsung or SanDisk, which have never let me down.
