I am sure that you have tried other posture trainer braces before, but this is unlike anything you have tried. Not only does it train you to keep good posture, but if you tend to slack, the posture trainer will remind you to sit upright with a light buzz. After using this for a while, your body should start to conform and you hopefully will be sitting straighter and standing taller. It is very lightweight and comfortable. Easy to put on with adjustable dual straps. If you sit a lot on the computer or play on your phone, this is for you! You can even wear it under your shirt without anyone even knowing that you have it on.
