Looks fun in the right location. However, I see it much like a PWC, fun for a bit but otherwise an expensive toy that wouldn't have enough practicality for me.
However, I have toys that fit category. I have a couple kayaks, a sailing/rowing dignhy, and soon a couple SUPs. All of those are toys with limited usefulness. The difference is that, for me, they are all relatively cheap. Someone with a lot more money than I may view the Iguana the same way. Cheap water toy.
