The price is actually decently competitive for a quadcopter with the bells and whistles he's including.
Battery life is about what I'd expect from a quad. I have a sailplane that I'm building into an FPV platform; using a 2200mAH battery like this thing is specced for, I generally get around half an hour of flight time out of a battery charge, but that's with a single motor and having the option to cut the engine and glide intermittently.
