Thank you for viewing! I am selling this because I haven't used it much. As shown in the pictures, it is generally in good condition, but as it is a used item, there may be minor dirt and scratches. Please purchase only if you understand that it is a used item. Velcro is attached to the back. This listing is for the main unit only. Operation has been confirmed.
