I have been using the K&F Concept mobile phone holder with my DJI Osmo Pocket 3 for two days now and am very satisfied. The workmanship looks high-quality and well thought-out — especially in this price range, I was pleasantly surprised. In particular, the combination of sturdy plastic for the phone holder and aluminum for the extension rod gives the entire structure noticeable stability. The mounting options are flexible and can be used in many ways thanks to multiple screw threads. I can use my smartphone either as a larger preview screen or to control my recordings. Switching between portrait and landscape modes is also easy and makes the setup very adaptable. The padded contact surfaces are a useful detail that reliably protects my devices from scratches. Thanks to the 360-degree rotatability of the holder, I can quickly find the right angle — convenient for spontaneous recordings under changing conditions. The larger screen makes filming much easier for me, especially when assessing perspectives and quick settings. The integrated cold shoe holder and additional mounting options allow it to be combined with other accessories such as a microphone or light, which makes my rig even more versatile. My iPhone is firmly in the holder, nothing wobbles. The entire system looks robust, well thought-out and is a real asset in everyday creative life. If you want to work professionally with the Osmo Pocket 3, this is a very good choice - so you deserve 5 stars!
