Selling my basically new back and neck vibratory massager. 10 strength levels, interchangeable heads, has a heat attachments and a cold attachment with a long life rechargeable battery. The thing that is best about this is that you can use it in the U-shape which works awesome on the neck and shoulders or extend the handle straight and you can get to the middle of your own back which is amazing. I bought this hoping my son with a bad back would use it but no such luck. Only used as demo one time. Come try it, you might like it. Cash only, offers considered.
