Thank you for viewing. This item has been tested and is in good working order. It shows signs of use overall, but is in relatively good condition. Please check the images. The sponge on the back has been removed to make it easier to apply Velcro tape. Removing the Velcro is quite a hassle if you want to attach it to the back, so this is more convenient than the standard version. The knob rotates easily, so a special sponge for the knob has been inserted. Please understand this. Everything in the images is included, and there is no box. It will be wrapped in bubble wrap for shipping.
