Basic key can be a little weak in the future but will tell lol, perfect to mount iso or otherwise, received very quickly key can be slow for some but will slowly go away and avoids copying or mounting errors wide color that is perfect for me like that I can write it to stabylo and recognize even if they are already colored and a slot in the back for passing a string Functional key under win 7 32 and 64 bit and under lunbuntu 14.04
