This was purchased years ago. It was hardly used. It has a max of 20 miles. My wife was nervous to use it. The 20 miles comes from me driving it around the neighborhood just to keep it working. I finally stopped and it has been setting for years. It is like new. It requires new batteries. They can be purchased/installed from Alpine Medical equipment. I have all the manuals it came with. Asking $200 or best offer. Murray location.
