I got a hold of one last week and it's pretty damn sweet!!
Here's my express review.
pros:
-it's tiny, flies safely indoors.
-can withstand crashes very well.
-decent battery life (5 minutes) on a 5-10 minute charge.
-very affordable.
-cats love it!
cons:
-way too difficult to control forward/backward speed.
-indoor air must be completely calm to operate.
-outdoor flying is nearly impossible.
-the controller uses IR, which requires decent line of sight.
-packaging and instructions are very cheap.
bottom line:
This is one of the coolest $40 toys you'll find! I'd love to see them workout the forward/back flight control, but overall this is a great start for this genre.
