Sandbox SMART R2 With box Used at home for about a year. When I opened it for maintenance, the wiring attached to the fan came off, and it was just returned from the manufacturer after being repaired and inspected in November 2025. There is dirt on the chaff collector and other signs of use, but there are no problems with the operation. Please refer to the official website for product details. As shown in photo 6: ・Sieve (used for cooling coffee beans) ・Tray x 2 (used for hand-picking)
