We have friends with one. We've played with it. It is fun, fairly easy to assemble and disassemble. However, it's very, very slow to paddle and much more work to paddle than a hard kayak. You will also get very wet, your bottom will be in the water.
I have pictures if you'd care to see them.
A good traveler has no fixed plans, and is not intent on arriving. ~ Lao Tzu
