BBstore Ergonomic Smart Posture Corrector With Adjustable Back Brace

OverviewFrequently Asked Questions If the posture reminder is not sensitive, you can tighten the strap appropriately, and at the same time, when initializing, the back should be straight and the chest should be stretched out as much as possible. If the posture reminder is too sensitive, you can loosen the strap appropriately. When correcting the setting posture, the vibration is frequent, you can sit upright, re-initialize, and click to power on. If the machine fails to turn on the machine, charge it for 10 minutes, but there is still no response. Please use AFTER-SALES SERVICE.
