I purchased this here, but I stopped using it after about a week, so I am listing it. There are no scratches, stains, or signs of use, and it has been disinfected, so you can use it as is. It's a full set including the main unit, charger, cords, instruction manual, and original box, all in beautiful condition. About half of the included gel remains, so I will include that as well. I have confirmed that it works, so please purchase with confidence. Thank you.
