My Qpad MK85 just broke

after 4 months. Heavy use though
The issues i had with this keyboard:
*Windows key doesn't work if you wish to use macro's on desktop.
*Unnessary noise created from the audio jacks thus making them useless as when you plugged the speakers/mic directly into PC they were fine.
*Sometimes a key which get constatly detected after just been pressed
I mean it's still a good keyboard but the bottom 2 shouldn't happen on a premium keyboard.
My backlights broke & before hand i experienced flickering every other day recently; i suppose thats fault related though.
