I've been using this K&F Concept phone holder with my DJI Osmo Pocket 3 for a few days now, and I'm really impressed with what they've put together here. The build quality is absolutely top notch, which honestly surprised me given the price point.The phone holder itself is made of plastic, but it's far more solid than most other third-party phone holders I've tried. What really sets this apart is the expansion bar, which isn't plastic at all but appears to be made of aluminum. It's slightly heavier than most other accessories, but in exchange you get something that's way more solid and stable than anything else I've used.The expansion bar has six metal screw mounts for 1/4 inch screws, plus two main screws for attaching to the Osmo camera and the phone holder. This setup gives you incredible flexibility in how you mount everything. You can have the phone facing forward to see what you're filming on a large screen, or facing backwards if you're filming yourself. You can also go either vertical or horizontal, which gives you complete freedom depending on what kind of content you're creating.Both the phone holder and the extension bar have soft pads to avoid scratching your camera or any other accessories you attach. It's a small detail but shows they really thought about protecting your gear. The phone holder also has 360-degree rotation capability, so you can turn it in every direction to get the perfect angle.What I love most about this setup is how it opens up infinite combinations with other accessories. The holder has two screw mounts, so you can attach it directly to a tripod or mount it to the bottom of the phone holder. There's also a cold shoe mount on top that works perfectly for a microphone, light, or any other accessory you want to add.This thing can be combined with other accessories like cages to create whatever setup you need. The possibilities really are endless, and you can make your rig as heavy or as light as you want depending on what you're shooting. For content creators who are always on the go, this kind of flexibility is invaluable.The larger monitoring screen makes such a difference when you're trying to nail your shots or make parameter adjustments on the fly. I've also used my phone as a teleprompter with this setup, which has made my video recording and live broadcasts so much more convenient.K&F Concept never disappoints when it comes to quality accessories for creators, and this phone mount is no exception. If you're a blogger, influencer, or anyone who creates content with the Osmo Pocket 3, this is definitely worth adding to your kit. Five stars without hesitation.
