Almost 5 stars
This is a actually a pretty decent product.  It's design is actually quite good.  And it has actually been helping me quite a lot but it's not as one-size-fits-all as it's advertised.  I'm a pretty commonly sized woman - I'd say close to the woman in the picture's stature - and yet it's slightly too bit. The fit is what makes it awkward, because it could have even fit better if the velcro just had a longer strip on each side.  Alas, it's a decent product and I'm generally still glad to have it.
