It was a hit, so we bought one for family friends for a birthday - high hilarity as we heard the reports from their kids - and then more for our extended family at Christmas. Shocked reactions around the Christmas tree.
The response has been amazing, people saying things like "How did I do without this my entire life??" and "How was I such a savage before??" On vacation at AirBnBs we are looking forward to going home just so we can have a bidet again.
In most cases, you don't even need the extra features, like fan or warm water. Regular cold water is nowhere near as bad as you'd assume.
