I bought 2 identical memory cards in August. The first one failed after 3 months in the DVR - it writes on an empty one until it is full, then it does not go for rewriting, the second one failed in the smartphone - when accessing it, it writes that the memory card has been removed. It's a pity, I've always been satisfied (albeit with SD cards) of this brand before, I was not lucky with MicroSD. I'm not going to risk anymore, I'll take something else.
