Very good value consistent speed compared to my other keys in 2-USB3 or fast delivery by the AMAZON-star less is too big for the green ring for nothing that increases the length of the key. Otherwise, it is very simple, visible and is fully in my wallet. By cons, white is very messy in contact with tickets in the same wallet, but I have not taken for its aesthetic and she always gives me satisfaction after 6 months of daily use.
