My wife dragged me to an appliance shop in the Mission (SF) and they had a toilet like this in their bathroom. At first I was shocked and appalled at how forceful the stream of water was - especially as I had it on the 'low' setting. Then I became aware of how long it was spraying because after 30 seconds I had to turn it off. With the combination of these two (and the heated dryer), I didn't have any problems.
