I didn't try it myself yet, but some freinds of me did.
It flies ok,but isn't that great.
If you crash the kite, the battens can break.
If you fly the kite with the little tube at the back of the kite, then it doesn't fly good. Without the little tube it flies better, but if you drop it in the water, the back of the kite can sink and you will have problems relaunching it.
If I know more about it, I'll post it.
Keep on flying
