Purchased three years ago. It works without any problems, but it's used and doesn't have the box. There are no pads either. Thank you for your consideration. 【For all athletes who challenge themselves every day】The AT-mini Personal is a device that supports daily condition management, essential for athletes to perform at their best.

You can care for yourself anytime, anywhere, whether at home, in the field, or while traveling. The lithium-ion battery allows for up to 12 hours of continuous use.
