New, Unopened Product Items for Sale: Air Pressure Adjuster for ROHO Cushions ROHO SmartCheck Retail Price: ¥20,010 Product Description (Quoted from the Manufacturer's Website): ROHO cushions require regular air pressure adjustments. This SmartCheck has a built-in air pressure sensor. It uses a light to indicate the pressure status when inflating, making adjustments easy. With the push of a button, you can check if the air pressure is correct. It can memorize the air pressure that suits the user, allowing for easy air pressure management. While air pressure adjustment is possible with the ROHO cushion body set alone, using this SmartCheck makes it even easier. This is an optional product for those who are new to air pressure adjustment or are having trouble with it. Photos 2 and 3 are of the actual product. The others are from the manufacturer's website. Important Notes: Cushion body is not included. (SmartCheck only) The SmartCheck can only be used with ROHO cushions that are SmartCheck compatible and have a dedicated connection port.
