Gopro say their "Hero 7" is a gimbal killer but that was until DJI created a tiny gimbal with a camera, smaller than my hand. I've had my teeny tiny DJI Osmo Pocket gimbal for 3 days now and I can say that I am exceptionally impressed with the footage I have taken in that short space of time.
If you are interested in making small movies of your climbing adventures or bouldering skills and you don't want the faff of carrying a mirrorless camera bolted to a heavy gimbal then you won't be disappointed with this little bit of kit.
There are tons and tons of reviews on Youtube but this one is my favourite and it was on the strength of this review that I ordered one.
