The one thing I dislike with the Mavic Pro controller is fumbling around trying to fit and connect my iPhone in the handgrips, when I do I have to remove my case. Also it limits access to the home button.
This seemed to be a great option, plus it gives me the feel, look of my other drone - having the device above the actual controller, I don't have to remove the case and I have full access to the entire phone. The grip of the mount to the phone is rubber and feels pretty good. The clip to the Mavic controller feels ok, some slight movement but not to the point where it feels like it's going to dislodge and fall to the ground. The biggest downfall for me is the screw on of the clip to the iPhone grip. This feels like it just comes loose on every flight swiveling the phone slightly. No matter how much I tighten it, I end up having to tighten it again after one flight
Since the screw is pretty long, there is no fear of it coming detached with the phone grip potion coming apart. It's just a slight annoyance right now. The $24.99 price, I do feel it's a bit pricy for this no so perfect construction. Since a lot of Mavic Pro accessories are dropping in price (this one hasn't - yet) because of the soon to be announced Mavic 2, I WOULD wait to see if this product drops in price as well. BUT if having the phone or small tablet jammed into the hands of the controller does drive you nuts - like it did for me. I would still recommend this overall.
