Must out my review of the other reviews say "just ridiculous !!" ... So just to understand: I order a "faucet attachment" for only 3,89 (dreieuroneunundachtzigcent !!!) and complain, that's the thing made of plastic? !! ?? .. and the most brilliant of the last sentence, and I quote, "engineering and craft services are This product is not recognizable. " ?? !!? I consider myself still with laughter !! So I would be in your place viell. also prefer to Vill. & BOCH gone ??! So I ordered three pieces. I am "only" a woman had, unscrewed with a pipe wrench the old metal top of my faucet, then by hand (without pliers!) Plastic LED attachment screwed tight and you're done !! Has four minutes gedauert..und it is close .. absolutely! (Simply ..viel.haben the "sealing ring with pure undergo forget ..?!? ;-)) Yes, it injected (slightly) more than before. The I reply simply by I hold a little less / more cautious Open the faucet than before (pure habit!), Then it does not splash .. and saves more water ;-) No: there is no "total reflection of the water jet" instead, but "up to one third" seems the water but in color. I think that's totally OK. (..I Will now look again viell. Night without turn on the lights in the bathroom, viell. Is the ray but then to "down" in color .. ;-)) .. Result: I am totally satisfied, fun and good mood in the morning the same (left came also during my visit to well !!.), And: For the price, of 3.89, rant does not determine that it is only made of plastic but order the same to me yet what to stock, IF my time break ..
