The product functions without issue, but as it is a used item, please only purchase if you are comfortable with that. Due to the size of the item, I would prefer to only consider those who can pick it up. If you are in another prefecture and need it, I can create the parts and pack them in a box. The reassembly instructions are easily found on YouTube, so please refer to those. This has 8 buttons and offers a full range of options to adjust to any type of relaxation. If you would like additional photos or have any questions, please leave a comment and I will respond. Overall, there are minor scratches and signs of use.
