This is the first drone I've owned, and I'm very happy. I actually can't believe all the Mavic does for it's size... I've been an amateur photographer for 2 decades and feel like the mavic is an absolute steal of a bargain.
I have had mine for about 2 weeks and about 10 flights, and zero issues. I love flying it. I am totally convinced that if I lose this one, I'd be ordering another the next day- I like it that much.
I have 2 other people I know that own/have owned drones, and BOTH of them experienced fly-aways and completely lost them (I believe both were Phantom 2's). On a third occasion, I was joking around about buying a friends Drone (we were talking) and he took me out to fly it- and it took off on a Fly-away. Took us about an hour, but we did find it.
That being said, I bought a Trackimo for my Mavic.
