I am selling the AIROFIT PRO 2.0, a respiratory muscle training device. It connects to your smartphone via Bluetooth, allowing you to train using the dedicated app. I've used it for about two months. Please check the photos for the condition, but it's generally clean. It works perfectly. The mouthpiece has been thoroughly cleaned. Includes: AIROFIT PRO 2.0 unit, mouthpiece x1, charging USB cable. Please consider purchasing, understanding that this is a used item. Thank you.
