A friend of mine bought a DJI Osmo mobile. I tried using it once for taking movies with my IPhone. I didn't like it at all. I found it is much easier for me to just use the IPhone.
I also have the dji osmo3I only used it once. You can’t take stills with it. I purchased it due to a left side stroke. I can’ support my camera,so purchased the new iPhone and was looking for a one handed device to allow me to take pictures again. My Osmo3 collecting dust.
I put in a Ring doorbell it works great. I can see them from the time they pull up to what they bring to the door it also leaves a message that they are on video.I Get notifications on my phone an can observe in real times as well as talk to whomever is at my door
