That looks cool kid!
"$499 until June 15th, then it will progressively increase up to the regular retail price of $999."
Not a bad introductory price.
There's a Polish guy here in work that does extreme climbing regularly and he says he can be up to 2 hours climbing at a time, depending on where he's at. Would you be climbing longer than the 20min flying time limit? If you are, you'd have to be able to catch and carry it the rest of the way. It's nearly 3 pounds in weight ( 2.8lbs (1.3kg)).
Here's a recent review of it at the prototype phase...

They seem to have released it earlier than expected according to that review?
But it does look like lots of fun!
