I followed your advice, Mark, when you first posted about this maybe over on Cool Tools, and I agree, it works great! A definite improvement on water pressure.
So when I visited my brother and used his shower with awful water pressure, I sent him one. He was dubious, but when he installed it and his wife used the shower, she proclaimed it was the “best. birthday. present. ever.”
So two enthusiastic thumbs up on this.
(Oh, and I never touch the little adjustment knob. In fact, I forgot it was there.)
