Purchased this product after having problems with a tight faucet handle which caused my index finger to swell from repeated twisting (have slight arthritis but this has made me realize how easy it is to cause damage. The Smart Faucet does everything the video and write-ups say it will do. It is easy to install-only takes a few minutes and much less expensive than buying a new faucet. Works very easily. I recommend it to anyone who has arthritis in their hands or anyone who has a pet who drinks from the faucet. Cats should be able to learn how to get a drink on their own and when they are done, the water will stop!!!
