I bought this one:
The idea is nice. BUT looking at the video again I feel misled. the image is stable, Yes. But thanks to the electronic gimbal attached. Not thanks to the stabilizer I bought!
I have tried adjusting the strength of the spring in all possible ways… it’s just crap. Short shocks it absorbs, yes. But One needs stabilization in walking etc. And when I look closely you can see the person really tries to walk as fluently as possible to not show that.
The only way it might help is on a bicycle, to absorb short shocks… maybe?
Anyway… want one? I don’t use it, for € 20 (excl. shipping) it’s yours
