We were initially quite skeptical, since we have such a hook used for the first time. So mounted and tested. My girlfriend and I had to find them useful to test something else. If someone claims to sell premium, then the goods must be Premium. So tested and they even hold up to 10kg and without problems (every man for himself). For the price, I can only say that it was worth it. Unfortunately, the car holds the 10 only not .... but so much need not carry you.
