Have 2 seats bought, because I trusted the tips of my Mitkäufer. The disaster began during installation. The mounting pins were too short when wall-hung toilet. Check with the supplier Thats Shopping GmbH: Delivery is standard, longer pins they can not get. I should try it at the hardware store. In no hardware store, there are those special pins. I can not recommend a purchase of these seats. Dear in stores and buy better quality.
