I use this gimbal with my iPhone 7 Plus and it works very well.

Hello I ordered this for a good price from DJI, it does a good job, no telemetry but iPhone is already included. Digitec is the best price in my opinion. All these products are Cina so I decided to go for this solution. Sorry for my writing, I am from Ticino.

Yes, it just fits in my opinion. It's "only" 1mm bigger than the compatible iPhone 6S Plus and also almost the same weight.

This gimbal is compatible with phones up to 5.5" the iPhone 7 Plus should work accordingly.

no... this version is especially for mobile phones... just enter FeiYu Tech on the page ^^ then you will also see these for Gopros

Unfortunately, this gimbal is not waterproof.
