Might be a new design, but not a new idea.
I bought a nearly identical looking shower head at Ace Hardware in 2001. I remember it being Made in the USA, but the brand eludes me.
With an ex wife who loved long showers it cut our municipal water bill by 20 percent. The big savings came on the sewer side of the bill.
They billed you coming and going on the water and the sewer side was twice as expensive per gallon as the water coming in.
