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 Output:
Good Review

It worked for a month, I can't complain. The first problem was that my new monitor would not pick up the signal, so i tried several other sources before calling HDE support (which takes 3 days!). They said it must be some kind of interference etc. So all i needed to do was return the whole system and get another since we were getting no signal at all. They agreed to refund my money. Well that's when things got really bad as far as customer service.

Bad review

I love this product because it does exactly what it's suppose to do! It's a great addition for you dog but if your going on vacation don't leave home without it! It will help keep the water in too! And best of all is that there are no harmful chemicals with this product. This is just my opinion! :-)

Ex Output:
Good Review
