Functional product
It is a functional product. It helps especially in the face of back pain, the posture correction I imagine requires more time (two weeks) if that is the case. Perhaps its main weakness is the way it presses under the armpit, so it is necessary to use a kind of foam that cushions this discomfort.<br />Since I use it, I consider that it helps me a lot to improve posture, I recommend it especially if you spend all day in front of the computer.
