I've used a lot of encrypted USB keys Kingston but this turns out to be by far the best, for the following reasons: - The encryption system is simple, you insert the key, a window opens faster, you type your PIN and then you have access to content, - The transfer times are very satisfactory, - Aesthetically with its metal cladding the key is particularly well finished and seems robust, the cap seems to stay in place even after a few uses. - It is relatively heavy (but it obviously excessive), compared to a plastic key, say that it is heavier, that I put in the positive (but that is a subjective characteristic).
