We have purchased Kohler faucets, sinks & bathroom accessories for years and always were happy with them. This toilet seat is a terrible design and a poor offering from Kohler. It sounds great from the description, removable for easy cleaning, a night light etc. I took the seat out of the box to put batteries in the lighting, removed one insert from the right side and the went to remove the left insert and the little plastic tab was broken already. I can't imagine they would last through very many removals for cleaning. The light was very dim, even in total darkness. It is a poor product and I am returning it and getting something not so gimmicky.
