Very easy to install on our kitchen sink. Took about 5 mins tops!  I love that I have 2 options when it comes to water; one coming out fast (normal) while the other is more precise. Since having this system on my faucet, I’m drinking more tap water knowing 99% of lead and contamination’s are not in my water! I have not experienced any leaking at all and hope it stays that way. I like that there is a light indicator when you use the precision stream!
