Review on 💧 High-quality Faucet Aerator Flow Restrictor Insert 40-Piece Set for Bathroom or Kitchen, Red(2.2 GPM) and Green(1.5 GPM) by Shane Wallace

good so I guess I've been lucky so far because I've had a problem with so much calcium for the first time in my life. in the faucet that I had to replace the aerators. I didn't even know it was a thing. :( Anyway, they worked great and after fixing a couple that didn't work I decided to replace them all over my house and was pleasantly surprised that they were all the same size even though they were different Branded faucets and had different uses (kitchen, bathroom, etc.) I didn't need 40 pieces too many, but I figured my kids and other family members might need some in the future.
