I have read the other negative reviews on this product, but want to risk it anyway. Short and sweet: 2 Cards ordered: a very defective (is not recognized by any device) While the other functional, but should not be like a class 10 card. Read-. was just under 8Mb / s, well below the what should be. In this sense, the second card is defective.
In contrast, I hae just now a SanDisk Extreme SDHC 16GB Class 10 memory card in the laptop: 30MB / s read, write 23Mb / s. So in this case, the strong buy recommendation for SanDisk and a "last to God's will bother" for Transcent
The only saving grace is the Frustfrei packaging. Only cardboard and even cheaper than the conventional packaging! Prima!
