The original Sony product (VCT-CM1) does not exist in Germany, and import that would have cost about 80, that was me then too much. This terminal was by Prime within a day for just 11 and is relatively compact, which is on the way but practical.
The terminal is well made and has a very high clamping force. They can easily be attached to objects of good 2-4cm. Concern drops something I do not have it.
Unfortunately, the design ensures that it holds without wobbling rather to thicker objects. On thinner plates or pipes it tends to bring me much wiggle / vibrate (wind etc.), as the support point then is quite low - which is important to always inserting the terminal to stop and so brings out the maximum stability.
The ball head is not that great and not really turn around, but he keeps very tight and is made of metal. The tripod thread was with me at the first turn not quite right, but now it comes.
Because you can rotate the base of the head 360 ° is as good as any angle of the camera possible.
Negative to mention would be the bestial stench of the product according to the most toxic chemicals that produced the Menscheiheit ... The clamp spent only once a week on the balcony ...
Otherwise, for most applications the GoPro / ActionCam thoroughly recommended!
