Ive had nothing but trouble with this keyboard. It will randomly disconnect…sometimes repeatedly until i physically disconmect and reconnect it. Several keys dont behave as expected, the dedicated media buttons will stick causing the entire playlist to skip as opposed to a single song. Both my keyboard and keypad are bad. I have a stealth controller and the flightdeck setup with pedals…all of which have been excellent, i cant tell you how dissappointed ive been about what i expected to be an equally great keyboard/keypad.
