I have a 1000 and a 1400. Both are great, the 1400 is better with the additional memory functions. I would be literally hurting without them. I go 4-5 times a day and the use of toilet paper made going a painful experience. I think the Gastro Doctors should let their IBS-D patients know about them, I suffered for over 20 years before I found the 1000. Also, my wife loves the heated seats. She has complained for years about the cold seat at night.
