Not sure
I have now tried a few of these posture correctors, and I think the ones that are of this type of design tend to be more or less the same.  That isn't really a good thing though, because quite frankly I do not see any big changes in my posture with these braces.  Perhaps at the time of wearing them I do, but not when they are off.  The other thing is that they tend not to be terribly comfortable to wear.  I find the straps will eventually chafe a little and cut off my circulation too.  I think the best solution for posture correction, is through exercise, and strengthening the muscles that will inevitably hold you upright.  This unfortunately, isn't exactly the best solution, in my experience and opinion.  I wish it were, but I haven't had any great results with this type of brace.
