Some comments made me hesitate to choose this otherwise seemingly solid usb and mini price. But I do not regertte my purchase. I use it for personal data storage. I always wanted one on me. I put it in my keyring and I use occasionally to store files. No worries for now. I think those who give feedback indicating that this USB key has failed and that the Chinese gear is not serious (What product does not come from China of our days?) Make hasty conclusions or scientist does not use with care these "precious jewels" technology. That said, it is highly likely that the series are bad, but then to generalize and take out the big words ("scam" product; "Chinese", "escape" ...) I do not agree and I want to emphasize here.
