Jessica 5 My landlord told me we couldn't put a heavy filter on our faucet....but the faucet's spray was really crazy and splashed water all over the counters and floor. So I got this attachment and was able to screw it on really easily. Now, the spray is much softer and can easily be twisted for one stream or multiple stream spray. It was probably the most useful purchase. Sometimes if you twist too hard to the right, it can come off and start leaking though. So just be careful to keep it tightly screwed in.
