Great product

My kid needed more space on her phone and this gave more than the phone came with for a lot cheaper than buying a bigger storage phone. Highly recommend.

Works quite well for price point. I have been using for 8 months now! Not one single hiccup. Their are other brands out their, but at this price point, and Walmart warranty on these, it hard to beat.

Reliable, and Efficient.

This onn512GB micro SD card performs well. So far, it seems reliable and efficient. I feel I can trust the card...unlike other storage cards that tend to lose your data. It gives me comfort knowing that I have my data and important photos in a safe place, that will not popup one day and say..."Format Disk to Use"!
