I love this thing. I just spent more for the one-head version for a second bathroom, and now I wish I’d waited.
Easy as hell to install (it’s tight enough that I didn’t need the tape). The ability to shut off water to either head (instead of just an off setting on the head itself) results in greatly increased water pressure, too. This thing makes it so we can do 5 showers back-to-back and not run out of water.
