This board is very solid and just like a real skateboard. The surface could have been made abrasive/rough to make it even better match to a real board, but other than that is solidly built.
The best part seems to be the way it attaches to the Wii Balance-board device -- it has two bi-axial joints similar to the joints in the mechanism supporting the wheels in automobiles - that allows more freedom than just having the board lie on top of the balance-board. The board can not move laterally which would be best, but still allows a good angle of tilting pressing on the balance board in different degree. In this way, it tilts just like a real skateboard, which I believe is more realistic than just pressing on the balance-board itself or pressing on a board that is attached "firmly" to the balance-board surface.
Like it.
Beware though from who you get it. Mine came from a third-party re-seller, packaged very poorly with a few scratches (however this is seller's issue, not product issue).
