Frustrating to put on. But works when it works.
The Velcro does not stay on.  I am constantly fiddling with it in order to stay in place.  The unit consistently slips as you go about your day and you end up having the pull it down from the back in order to align it properly again.  Additionally the straps are supposed to go through some slips at the base of the back of the unit and then wrap it under your armpit and onto your shoulders, but you cannot put on the device without having the unit pre-set so it is very difficult to initially put it on, and then the Velcro is undoing itself as you try to put it on... very frustrating.<br /><br />The good thing is once you have it on and it's working properly, the unit works.  It has alleviated a lot of my back pain and has helped my posture while sitting at my desk or going out and doing errands.
