I truly loathe this kind of plastic twist-the-dial shower device. The outer smaller wheel is for turning the water on and off…fine. And you have to turn the larger inner wheel to the left to get the warm or hot water, but you have to keep turning it and turning it before anything happens. One revolution, two revolutions, etc. And it sticks. This morning I turned the crap out of it and I never felt any seriously hot water at all, and then I turned it some more and the water turned tepid and then cold.

Is this invention a nouveau riche Utah thing? Remember the old days when you had two metal-chrome controls, one for hot water, another for cold and a third for switching between shower and bath water?
