This is the second Biobidet BB 2000 that I have purchased. I bought the first one a year ago and my husband and I love it. My dad fell and broke his hip so I have installed the second BB 2000 in my hall bath for him. He is much happier that he doesn't have to rely on someones help when toileting now. The unit is easy to install and takes about 10 minutes to have it up and running. The night light, heated seat and constant warm water are wonderful not to mention all of the wash features. 
This toilet seat has spoiled me and I no longer want to go and sit on a regular toilet seat.
