Missing some basics

The "joint" is a good idea but way too weak and deosn't hold up well When traveling. I drove up to Scotland and back to Germany and had to stop using it. The second and biggest problem Is that it comes out and you lose power. It needs a ring of "rubber" to hold it in place like some other products: such as this have. A redesign and a couple more euros on the price and it would be a super product. As it is - average.
