At first I was very surprised at how heavy and solid the toilet seat. All predecessors toilet seats were significantly lighter (and nearly as expensive). In the past 5 years I have purchased 3 seats because these wobbled repeatedly, ie the brackets broke, had to be tightened again and I still always felt the same, together with seat to land next to the Toi. Equally frightened me the items for assembly. But after briefly studying the instructions it was almost as if by magic. In fact super easy, even simpler and easier than any previous models.
The lowering system is a bit slow but Ansonten the best toilet seat for years. Budge, do not wobble and is very easy to clean. Will order it again, but I hope that this will happen only in years.
