I truly love this faucet! I was able to put it in without my husband’s help, in just 45 minutes. It would’ve taken less time, if the black wrench would have fit the nut correctly. I used a crescent wrench which took time and was a little frustrating. However, once the faucet was in, I will never go back to a sensor free faucet. I waited about a week before writing my review to really give pros and cons.
