What is lacks as you might imagine is some refinements here and there, and helpful instructions. All and all it is great and very rigid when inflated to about 5 psi. Although the material is heavy duty, it totally feels like a river raft, I do wonder how it will age, with UV exposure and time. And it’s not like it will be set up all the time, I’m just a weekend or vacation user. By the way you can’t really walk on them well, even though it’s rigid, it moves all over the place but it b is good for working on your balance!
