Review on 💪 ConfidenceBoost: Upright Corrector Strapless - Stay Discreet and Correct Posture Effectively! by Edwin White

Product does what it says on the tin. I put it on, forget it, and then it vibrates when I lie down. It's simple and effective. The app is easy to use. I have been suffering from back pain for many years, after using this product for 2 weeks I definitely feel an improvement. I found that even when the device wasn't with me, I became much more aware and found myself bending faster. Tip: By default, the device has a 5-second delay before vibrating when you bend over. I found it a bit low so I set it to 15 seconds, which is perfect (you can easily control this from the app).
