This device was returned because my K7 not reading correctly. The sound is interfered with by a huge noise, like a player on the other, impossible to clean the computer. My k7 are old but are not involved. I tested their basic playback on devices that unfortunately do not have the necessary connections for a correct connection to a PC. The ION platinum is simple to use, it is not at the settings that we should find out where the problem lies. The software is also super easy to install. It is this facility that is 1 star.
