[EX Q]: I have the largest version, and for my purposes it is perfect. Only complaint would be that the sides are not rigid enough, so the top of your head will probably slip sometimes. It does its job well in keeping you dry (and it's very comfortable) when swimming. Would recommend even with small problems.
[EX A]: Good Review

[EX Q]: I bought this product and the directions are vague at best. The pictures they show with it don't correspond to what it looks like when applied. Also, there is no mention of anything about bubbles that might get caught under it. Very frustrating. Would give zero stars if option here.
[EX A]: Bad review

[EX Q]: This is the most frustrating item I have ever purchased from Amazon. The picture clearly shows a full back brace but does not indicate that it contains some kind of gel insert. If there was any kind of gel you would think this could be comfortable. In fact what feels like one of those things made for people with high level tennis elbow, feels far too hard for someone who has arthritis. It also had quite visible seams which are very uncomfortable.
[EX A]:
