Let me start off by saying that I've never actually used this product. Here is my problem with it...if a product like this actually worked then there is no way the NHL would approve it for game use. It isn't giving anybody a competitive advantage. When skates are sharpened there is a coating applied to the blade on the last pass that more or less ensures a super smooth finish on the blade...I don't see how a liquid coating is going to save your edges. Besides the fact that they will wear down no matter what, you will always get nicks and burs from other skates, sticks, goal posts, benches, boards etc. On increased glide, I'm sure it has some affect, probably so minimal though that it will be impossible to notice. Just my opinion.
