Review on 💾 Sony 16GB Class 10 UHS-1 Micro SDHC Memory Card (SR16UY2A/TQ) - Up to 70MB/s Speed [Newest Version] by Alan Sitton

This card worked for 12 months in my mobile phone and then it became "read-only" which made it unusable. I have dozens of memory cards and USB sticks, some of which are many, many years old, and this is the only one that has failed this way. I consider this to be defective and poor quality but as it is a year old I cannot return it to Revain. I thought Sony was a good brand but apparently it's not. I'm replacing it with a SanDisk card, which I've never had a problem with.
