Used controller which has problems. Sold untested . I do not have the equipment or expertise to check this unit. It does look as if it has been dropped.The right side handle is bent inwards and the black buttons on that side of the front panel are stuck in the on position . I believe it has suffered damage inside so I am selling this unit "as is" For parts or repair. No warranty offered and no returns will be accepted . Any and all repairs the unit may need are the sole responsibility of the buyer. By committing to buy you are agreeing to these terms . Sorry no instruction manual or other accessories. Cosmetically clean with minor scuffs and scratches.
