Washes two bottles at once. Made of black plastic, looks like brass on the photo but it is plastic!
Sits flat on in the sink, put the bottle on and a fine spray of water jets up into the bottle.Turns off when you take the bottle off so you don't get water blasting up your sleeves.
Fast and easy once it's set up. Needs a screw tap like the ones that take the hose pipe fittings
