I have this memory stick for a year and it never failed me. Its small size is very convenient because I can store in the small coin pocket of my jeans (for example). Lexar 2GB JD Firefly has nothing to envy of her sisters known brands. Indeed, it is recognized without problems in all types of PC and its transfer speed leaves me speechless (1MB / sec, except when it comes to manipulating archive size exceeds 100 megabytes for which the transfer rate is then be a little longer). The electric blue flashing LED when in use makes this particularly attractive key. In short we have a great product.
