Today I've got a GoPro Karma Grip, an image stabilizer dedicated to GoPro cameras. Now, he is not the only one on the market who knows how to do this. Almost all manufacturers of electronic stabilizers have a model for GoPro cameras, less DJI that has its own solutions. Karma Grip is a very useful toy if you are already caught in the GoPro ecosystem. That is, if you have at least one 4th generation camera or even the latest model, and perhaps some accessories. This is the most useful but not the cheapest solution to stabilize the image of a GoPro.

I compared it with an OSMO DJI, a complete solution that with a 4K camcorder as well as a GoPro gets the same money, but I also had a handheld Chinese phone stabilizer, which with little adjustment can support A GoPro. It behaves the same at the level of stabilization, Karma is a bit better than the Chinese one. It is also significantly more expensive, slightly over 380 USD. And I can say that it is even more versatile than OSMO, GoPro can be put off the handle and you can use it on the helmet or anywhere else.
Would I take that? It depends, if I did not already have OSMO and that Feiyu, maybe it did. I need electronic stabilization for at least one of the small cameras I'm filming with. What if you get that? Probably if you have a GoPro. It's the best solution. If you do not have GoPro or do not plan to get one, then do not.
