I bought this with high hopes of not having to touch the faucet at all. We previously had a Delta which we could touch with a finger, elbow or my arm to turn it on. I have a compromised immune system so these type of features are important. However, this has the sensor on the left side and with wet hands, you leave drip marks all over the brushed  metal. Which makes having to constantly clean the drip off so water marks are not left.
