Very good. I put it in a moving vehicle (safari) and I am very satisfied. It tightens very well, has a sturdy good construction, and does not move; where you put it, it stays.

Good value for money if you compare it to an authentic GoPro. The extension is not stable enough and the clamp breaks somewhat easily if pressured. It does its job just fine.

Sturdy construction. More than enough for an action camera. Provides great flexibility in where you can mount your camera.

It looks fine for its price. Very practical. I haven't had the chance to use it extensively to evaluate its durability.

I bought it for mounting on a bicycle handlebar. I was not satisfied because it is not stable and I constantly have to readjust it to avoid obstructing the view of the sky.

Very good for the money, sturdy construction. Very good imitation of the original. And a tripod that comes out of its base!
