Terrific!! Especially for elderly folks in colder environments, but....being a man, I only sit down in the bathroom once a day, so it's wasteful to leave it on all the time, but....I really don't want to have to remember to turn my toilet seat on and off every day, or get up and have to wait for it to warm up every morning....so it's always on!! A timer would be very useful. Also, the cord should be 1 or 2 feet longer. All that aside  - I LOVE IT!
