Review on Strack Smart Posture Trainer and Corrector: Track, Correct, and Manage Your Posture with Ease by Carl Estell

However, it has problems syncing to my phone and saving. I wore a thin racer bra and used a magnet. Eventually, however, the magnet fell off. Self-adhesive stickers work better, but you can't put lotion on your back and then apply tape. It doesn't slip or stick. I think the connection problem is because there are too many devices connected to my phone via Bluetooth. Customer service has called me several times to help me resolve these issues. I will try another option. If that doesn't work, I'll send the item back.
