Reaction Low-Flow Showerheads

“a turbine-powered engine infuses energy and velocity into each and every spray”

So, does this thing require batteries, or does it just violate the laws of physics?

There’s a video on this page. Looks like it has a water-powered spinny thing.

*The Speakman Reaction Shower Head is scientifically engineered to not only function with low pressure, but flourish with it. Our team of engineers developed a single function spray setting that concentrates and optimizes water pressure, creating an exceptionally high-pressure shower head for low pressure installations. From the moment water enters through the fixture, a turbine-powered engine infuses energy and velocity into each and every spray. The result is a powerful, pulsating experience that performs brilliantly with low pressure. *

water comes out and it looks nice but there is no super charged turbine thing that made the water have any more pressure than my former shower head. Not impressed but already tossed my older shower head so it is what we are using.
