I bought this 4 or 5 years ago. I haven't used it at all for the past year or so, so I'm putting it up for sale. I wiped it down with a disinfectant wipe, but I haven't been able to remove all the dust that has gotten into the small crevices, so please refrain from purchasing if you are looking for perfection or are concerned about minor details. The original price was 34,000 yen. I have confirmed that it works. I will include the batteries. It's a simple exercise where you just sit while watching TV or reading. Thanks to this, my family member has been able to walk for longer. Individual results may vary. Thank you for looking.
