This Elo Pro System has only been used once. They are in like brand new condition. They have been sent to Poshmark for authentication, and returned to me as good for sell. There are to many wonderful things to say about this product, but I would recommend that you go to EloPro.com and watch the video and read all about it there. The device works wonderfully. This system is only a few months old. This system retails for over 1,000.00 dollars.
