Does it's Job
This product does what it is supposed to, pull  the shoulders back to assist with proper form.  The material is surprisingly soft.  The only thing I would like to see changed/added is the ability to adjust where the straps sit at the front part of the armpit.  I have fairly broad shoulders and torso I feel is on the longer side.  The straps tend to dig in a bit at my armpit.  I could probably wear it for longer stints or even all probably if it were looser in that area.
