VERY NICE LIGHTLY USED UNIT. GUARANTEED TO WORK AS IT SHOULD. TESTED IN OFFICE . NO CORDS . GREAT PIECE OF VERY VERSATILE EQUIPMENT. I AM A CHIROPRACTOR SELLING SOME OF MY EQUIPMENT BEFORE RETIRING. UNIT IS GUARANTED TO BE GOOD. ONE OF BEST PIECES I HAVE EVER HAD. I STILL HAVE 2 THAT I USE EVERYDAY BUT I AM GETTING READY TO RETIRE .
