I installed this faucet to replace an older kitchen faucet that was leaking despite having replaced all its gaskets.
Installation of this was relatively easy. I was concerned that there wasn't much space to mount the faucet in but that wasn't a problem at all. I followed the directions and its detailed diagrams carefully and everything worked perfectly the first time. Several weeks later everything is still working perfectly.
It took a day or two to get used to the touch feature, but once the family did everyone liked it better than a regular faucet. You can was dishes, bake, cook, etc. and not get the whole faucet and counter full of water and grit. Just a small spot you touch on the faucet gets dirty which is then easy to clean. Our younger son who can't reach the faucet handle is able to touch the faucet arm and he can now wash his hands, get a glass of water, etc on his own.
I installed C cell batteries in the battery pack. The directions say that they should last at least 5 years. That seems like a long enough time for me to use the battery pack that comes with the faucet vs. buying an optional plug in adapter to power the touch feature.
