Wonderful toilet appliance
I have had one for 3 years, it is superb.  Very well thought out and works flawlessly.  I liked it so much that I recently bought a 2nd.  I don't mind the extra bulk, compared to others, it is streamline.  The seat is designed well, for men who leave the seat up, when it is put down, it floats down slowly due to dampening. What I don't care for is the plastic material used in the seat, it should have been a harder material. It can scratch and it would be a nice improvement if they used a better material for the seat.  This item easily deserves 5 stars if not for the seat material so I had to give 4 stars but I wouldn't switch brands just for the seat quality because this beat the competition in every other way. It is durable and should last for years.
