AccsoonSeeMo 4K HDMI Adapter, 4K 30fps /1080p 60 FPS HDMI Video Transmitter Adapter for Phone iPad, Support Real-Time Monitoring/Live Streaming/Recording/Sharing, SD Card Reader (iOS12 or Later)

The device works really well, but is still heafy on a camera with the phone. Please keep that in mind. Some things they could improve.a) when you start the app up you have to choose the right SeeMo and in my case I have to scroll. I which there would be an app, update with settings where you can set the default or it would somehow detect the device automatically.b) I decided not to use the hot show mount as I do not want the endanger that that gets damaged. It seems others have no issue with that. My cage comes with a hotshow mount, but it is angeled, so its unusable. I could screw in one that is paralllel to the camera and use that. However I decided to use a Nato rail and bought a clamp similar to the original one that has a natoral. That I realy like a lot as it has a lever that makes putting it on and off real easy and secure.c) There are no cables with this device and I think they should have an option to chose the right one for your camera and it should be included in the package.d) I have a shockproof case on my iPhone that works really well but pushes a bit the boundary of the width of the clamp. Luckily I also have a string on the camera, and as I like to use this outdoors on a kayak, I will attach it to the cage. I wish there would be some loop so one could also attach this with a string if you use the coldshoe mount. This is the reason I went for the Nato rail. Maybe they should have the option to use either a cold shoe mount or nato rail

I am not able to test this device yet even though I have it on hand.The marketing needs to be clearer that a NP-F type battery is required for this thing to function in any capacity.I have looked around for camera-mounted monitor displays. Many are able to consume 4K HDMI inputs (like this product) but none use higher resolution displays than 1080p displays, and none of the remotely affordable ones are OLED. Given that an iPhone has 6 to 7 inch screens that are OLED (for good color), reach to 1000+ nits for comfortable use in outdoor conditions, and have somewhat higher resolution than 1080p, if the SeeMo can deliver resolution beyond that then I will be happy. I'll be back to flesh out my review once my battery arrives and I am able test the product.

I got this for use with Jetset and absolutely love it. It saved me so many times when I needed a monitor while on-set. I can use my phone or iPad and a quick video recorder at any time.
