I already own a Lexar 8GB which I am very satisfied. I wanted me to get one with more memory and 3.0 for the transfer speed. So I turned to it. Rather pretty, very compact, possibility to attach a small strap to put a door key, I was quite satisfied. Until the first connection .. The key is in fact the central column, surrounded by a small fragile plastic shell. You have to press the button with the small triangle to open the key, but on insertion thereof, the shell is a little shaky, and we dare not forcing. The system is not very strong, and I fear a break in the weeks / months ahead .. hence the withdrawal of 2 stars, because each insertion, I'm really not serene, and it's really painful . I advise to look to other models.
