I think it's a pretty cool drone. And for the price, you can't beat it. I have the Mavic Pro (original) and the Mavic Air, so I won't be buying one. The Mavic Air is pretty small as well, and does everything the Mini does, and then some, so I have no need for the Mini.
I'm not knocking the Mini in any way shape or form, but smaller drones, like the Mavic Air and Mavic Mini, wind has to be a consideration. As well as those who like getting really good distance, just from my own use, I know Wi-Fi drones are a little disappointing. So for those 2 reasons alone, I find I use my Mavic Pro more, because I just feel more secure due to the wind strength and flight time.
That being said, I like the price, size (despite it's wind concerns) and flight time (how do they get 30 minutes out of those tiny batteries ?) of the Mavic Mini. I basically bought the Mavic Air due to it's size, camera (some say it's better than the original Mavic Pro) and safety (I like the front and back obstacle avoidance). The Mavic Mini just doesn't offer me anything that I need.
