I write product reviews on YouTube and bought this product because I mostly take photos with my iPhone. It seemed to work great but I was very disappointed. The biggest problem I have is Rhino ROV forcing you to use their mobile app. The slider ONLY works with their mobile app and you are forced to use their mobile app's camera features. The app converts your footage to 1080P! You can't record 4k with it. The app forces you to use only a standard camera lens. Telephoto and wide-angle lenses are not possible! Also, the app is buggy. I had to restart the app several times because the record button stopped working. I'm also very frustrated that you can't reset the autofocus or autoexposure once you've manually changed them. The rest of the hardware is decent. The workmanship is solid with a very powerful battery. Unfortunately, the slider isn't exactly smooth, so if you're shooting something very close to the camera lens, it will look choppy. .
