Instructions on use is much improved....
After this review the company revised their instructions so they are larger, and easy to follow.  This is a great improvement in being able to use this product correctly.  I did wear this but still found that after one hour or so, the straps loosened so I had to keep adjusting them.  Also the strap that goes under one’s armpit started to hurt.  I asked several friends of varying heights and weights, to try this product and they had similar feedback re: discomfort under the armpit when wearing it for more than 15 minutes.  I really like the idea, but perhaps consider narrowing the part that goes under the arm pit and widening the part that goes on top of the shoulder... Not easy to do as there are so many varying sizes of people.  The posture corrector is useful when sitting and working on the computer, or doing something at one’s desk.
