I had a blue frother, I timed the time to fill a one-liter bottle with my mixer / maximum flow valve. my old blue so almost put 5 seconds. that acquired so green here Grohe put on sale at almost 15 seconds to fill it! so I logically divide by 3 my water bill on my kitchen faucets and bathroom (sink especially not to bath :))
I am more than satisfied so after regular access to product longevity but cleaned overnight in white vinegar should I make it last a long time ... however the jet power is much lower even with the air being sensible insuflé) than my old aerator but it's still more than enough to do the dishes or wash your hands ... that you ask for!
