I never thought I’d say how much I love a toilet seat but here I am “I love this toilet seat”. It has an automatic timer so whatever time you set it at it will come on every nightday at that same time and remain on for an 8 hour period. Both the lid and seat are slow closing. It was very easy to install. I am a disabled female and did it myself. The air freshener smell is very faint and goes on for about ten seconds. Highly recommended. Very happy with this purchase
