Hipee's Smart Posture Correction Device is here to help everyone achieve perfect posture with its thin, lightweight, and innovative design. The device runs on a rechargeable battery, connecting to your phone via Bluetooth. Personal customisation and a professional posture correction course allow Hipee to help you correct back and shoulder body posture; when your body deviates 5 to 20 degrees from correct posture, an intelligent reminder will vibrate quietly to adjust yourself.
