The cover I've ordered directly from WCShop24. Ordering was easy and delivery is very fast. However, the mounting of the cover according to the instructions proved to be useless. The lid slipped and wiggled. The only remedy was the supplied plastic plugs, actually on the bottom to screw should be required to simply put on the top in the mounting hole on the toilet. Assuming the diameter fits randomly. Otherwise, there is the possibility to buy a suitable fixations or even tinker. In any case, the mounting hole should have only 6mm diameter. For fixed screw on the lid I've used in addition a thick large stainless washer at the bottom. All this was supposed to be doing in Lieferummfang, then everyone could attach the lid Easy. At the end is still negative should be noted that the hinge did not match the picture on the internet. It is wesenlich simple in execution. I hope not rust.
