Love, love, love this faucet! Did a mini-redo of kitchen and upgraded to this great faucet. Had contractor install, and he had no problems, but I think it could possibly be tricky for a DIY project. The faucet works effortlessly and is so convenient to use. The spot-resist finish really looks good, too. It uses 6 AA batteries to power the motion sense technology, and my contractor said they last quite a long time. Of course, there is also a handle to use if you don't activate the hands-free option. I'm very happy with this product and would highly recommend it.
