I received this a few days ago. I opened it and used it once. I bought it because I thought I'd be able to fall asleep comfortably, but unfortunately, the neck height doesn't suit me... That said, I don't have time to use it during the day, and I don't think I'll be able to use it properly, so I'd like to pass it on to someone while it's still in good condition. Thank you! - Model Name: MD-600 - Function: Full body massage with air bags - Massage areas: Neck, shoulders, lower back, buttocks - Positions: Can be used lying on your side, back, or in any position you like - Controller: With remote control - Color: Ivory
