    All as in description. The device is a bit big, but the straps are a bit small (I wear it outside the clothes). Its work well. It vibrates whenever the upper back angle overpass the programmed threshold. But a fundamental disadvantage of all this type of devices is that whenever you are doing sth that requires you to lean forward it vibrates. All in all is a good product to help you to improve your posture in long term.

    If you have general posture disorder, if you think you're too bent over the keyboard, I'd recommend that you'll soon be aware of your posture

    instead of reminding, it could just simply pull or do something. or nothing at all.
