Works for teenagers well
Bought one for my son, he is 14 years old and spent a lot of time in front of computer. Couldn’t handle his rounded shoulders position and I see huge difference. He didn’t want to wear it at the beginning but I found the way to convince him and looks much better. After few days he completely forgot that he even if has this device on his back. I hope he will develop good posture.
