We've got this one at less than 34.00 it is the bottom of the market. It does not heat the water or have a special spray pattern. It is simple a valve and squirt of focused water jet.
It works well, however when January brings cold water it can give you a bit of a shock. That is only a brief moment in the calendar, though. I would rebuy.
