I know what can go wrong with a piece of metal. but there is so much cheap stuff (in the wrong specs/sizes) sold everywhere that one can now only rejoice if something fits their basic needs. So, I confirm: This works great for Mercedes GL450 OEM wheels (2011 model), the threads appear to be solid, the coating appears to be solid, the shank length is correct. And the price is great but you already know that so read the review to make sure it gets delivered :)
