I also owned a Karma Gimbal, but returned it because it was too buggy, and the iSteady was a better design for my use.I mostly use this gimbal for recording bouldering with a GoPro. I mount the gimbal on the end of a large monopod so the camera can be lifted about 20' in the air. The gimbal keeps the camera nice and level. This means that I want a 1/4 20 lug on the bottom of the grip which this gimbal has, unlike the Karma gimbal. This gimbal can also stand up on its own unlike the Karma gimbal.The app is also neat, but I don't end up using it much.Battery life is excellent compared to the karma.The thumb screws can be a bit fiddly at first, but once you get used to them it's not bad.I broke it. It doesn't like salt water (duh). I was hanging it over the side of a boat at the end of the monopod. It took a decent size splash and the pitch axis died. I could feel heat from the axis cover and the grip. I saw no smoke at the time. Once I got it home I popped the cover off the side and pulled the axis controller board out. There is visible damage to the PCB and what's left of some component after letting the magic smoke out (I guess I just didn't see the smoke at the time).So I broke it. My fault.I still recommend this gimbal very highly.If you can keep it dry, at $99 it is an amazing gimbal.If you can't keep it dry, maybe you need a $200 gimbal.
