I havent use it yet, but I bought a case of it and will start using it next season.
I have been using SeaDoo XP-S, but @ $48/Gal, I have been looking for something else.
The Mystik sells for just $19.99/Gal and has the same ratings as XP-S.
If it has the same ratings, it's atleast as good as XP-S!
There are a couple of people on another forum that have been using it all year and don't have anything bad to say about it..
I think Mystik is going to take over the market with this product!
