## Questions & Answers

### ⭐⭐⭐⭐⭐ Review
*by L***E on 27 December 2025*

I bought this memory card for my Samsung tablet. It fits perfectly, and is recognized by the machine. As far as I can detect, it works perfectly. It was a very reasonable price for a quality chip. Because it is so small, the opening in the tablet was a little tricky to deal with, but installation was still easy. I would recommend this card for lots of extra memory.
