I have 4 Brondell bidets. The first is a Swash 600, two Swash 1000s and now a Swash 1400. Each one is better then the next with better features. They all do a great job.
I have seven fused vertebra the result of 12 hospitalized surgeries and over 40 out patient procedures. All thought the bidet has become a necessity for me it also is for my wife who hasn't any limitations.
I bought the first one for her as a birthday gift. She and I became addicted to its hygiene. We have bathrooms on three different levels. We both would go to the third floor to use the bidet in her bathroom. After you get use to a Bidet, you don't feel right not using one all of the time.
The Swash 1400 we have at our lake cabin. The features for two separate users settings is most convenient being the only bathroom.
It isn't a luxury, its a necessity.
