I purchased this model at an electronics store when I hurt my arm because it allows for hands-free use. However, my body recovered faster than expected, and I only used it for 5 days (5 times). The condition is excellent, like new, but I have disposed of the box, so the item is just the main unit. - Disinfected with alcohol - Will use anonymous shipping - Hands-free capable (see photo 3) Please feel free to ask any questions in the comments. ^ ^
