Review on Delta Faucet RP18508PB Aerator Polished by David Banks

I have a white Delta faucet that is about 8 years old. The aerator was a bit clogged so I thought so , instead of cleaning it I would replace it.I found and ordered this red 2.2GPM aerator from Revain.It arrived about 30 minutes ago but to my great surprise it's not red but green.These Items are color coded Red means 2.2 GPM Green is a lower rating I think 1.5 GPM but it could be 1.2 GPM I opened the envelope it came in, installed it on mine tap and then filled the one gallon milk jug as best as I could. I had about 50 seconds. Then I reinstalled my old aerator 2.2 and got about 30 seconds. Much quicker! Yes, there's something wrong here! It says on the little shipping envelope "2.2 GPM". The aerator itself printed 2.2 GPM. But that's certainly not 2.2 GPM! Green is a red flag to me (pun intended). Return!
