After only 2 times use (at home without load) I noticed the part apart on the middle connector. I could see the end stops again stick (usually they are just tricked). Shortly thereafter, I noticed the bar then also at the bottom joint apart but could be time no longer fix this because wedged the end stops and not without tear out of the blue end - and thus destroy the whole staff - were removed.
The result: the compound dissolves continuously and wiggles around. You have to be afraid that you lose GoPro !!!
Another shortcoming: the holder on which the GoPro is attached, can be in spite of correct tighten still without problems by hand adjust ...
I recommend the product further in any case. I now take 15-25 more into their own hands and buy me the Sandmark poles, of which I have heard so far only good and it makes me a better quality impression.
