Review on Posture Corrector For Men & Women: Portzon Back Brace For Pain Relief Of Neck, Shoulders. by Sam Faucher

It does appear to do what it is advertised to do. It pulls your shoulders back and provides a support for the spine to keep it aligned through the upper back. So, that is the good part.With no instructions it can be a but of a bother to figure out how to use the first time. It also can be uncomfortable is you are a larger person and especially so under the arms. I used to load and transport large gas cylinders for a living and so am a bit more developed through the upper arms, shoulders and chest than most people. So, that might make this more of an issue for me than for most people.I tried with a thicker shirt but that did not help and tended to create wrinkles that just caused one more area of irritation when they were pressed so hard against the skin also. So, while the back support worked well, and it did hold my shoulders back some, it was also quite uncomfortable.I let someone else with a more average build try it and while they agreed that it was a bit uncomfortable under the arm pit area, their experience we not nearly as uncomfortable as mine. So, maybe it is a good product for your average person but definitely not for a body builder or someone with a larger chest and arms.
