Review on Memory card ADATA microSDXC 64 GB Class 10, V10, A1, UHS-I U1, R/W 100/25 MB/s, SD adapter by Adam Kardasz ᠌

Bought a copy. When checking at home, it turned out that the recording speed jumps along a sinusoid from 30 to 60 mb / s, the download generally drops to zero by the end of the file. I handed it over under warranty, opened the second card for a replacement right in the store, the same one-on-one diagram. Either the batch is defective, or in general all products are like that. We checked both cards on different readers, different files and computers, the picture was identical each time. Attached is a photo of this beauty.
