My dog LOVES flying *anything* - well, except birds which she thinks are her friends. Most RC Helicopters are too small for me to operate well. It's not her, it's me for sure. When I saw this it was bigger than the ones I failed at controlling and ordered it.It's a good size, larger than the ones I had before. The operation is easy - you turn it on, turn on the remote and they'll flash when they've synched, just a few seconds. Then you shift down and up to get the helicopter off the ground. And your flying! You can move back and forth pretty easily and up and down. I still over-react when it gets close to something. So I've run into a chandelier, a wall, and the stairs. I guarantee you it was all me. Lol. I'm getting better at it though. The point here is the helicopter has made it through these disasters with no loss of life and in good shape.It comes with two batteries that are easy to switch out. Our previous models made us unscrew the battery compartment which was a chore. This is a quick snap out and snap in - doesn't even really register. It uses standard USB-C to charge the batteries, so I already have chargers all over for it.My dog adores this and her snout has hit the blades a couple of times as she's barking at it. She has learned not to put her snout there and has suffered zero injury, which is also nice for me. The blades just stop when they hit something which makes me feel secure letting her have fun with it.This is a great toy and we have enjoyed it moments after we unboxed. It's great for kids, adults, and their pups. We're a fan.
