I researched a drive by comparing them all, I wanted to move towards a m with wifi and internet connection but the pb is by reading the reviews and features, it's seen that they are not reliable .. . So I opted for this one !! Perfect quality product !!! Read all the files (mkv, avi etc ..). M I use it with USB key 64GB. The menu is clear and simple. For files .rar think to compress so that the reader can read them !! I do not regret my purchase and highly recommend it !! New product with already happened a hdmi cable !!
