Sorry if you're intested in a device to accomplish the stated function, keep looking...as this is junk...I received the item 3 days ago..and haven't been successful in using it...the idea is good...but even with low water pressure on my faucet...as soon as I get it attached and turn on the water -- even slowly -- the apparatus pops apart and you have water all over your kitchen...the screw on fitting remains on the faucet... the flaw is in the design - the part that attaches to the screw-on collar has very little variance - and either that bit of pressure pops it off-...or --- where the two elements attach don't allow for ANY moverment..I really tried everything --- and it was very disappointing...I will be returning it tomorrow and look for a higher quality design
