I love the look of this faucet.  I bought it mainly for the touch feature and design.  As many others have mentioned, it does come with flaws.  We have only had this faucet installed and in use for about 6 weeks.  The most frustrating thing is that it constantly turns itself very quickly, so if you have dishes, pots, pans that require hand washing, get ready to have to constantly be turning the faucet back on.  I wish there was a way to adjust the length of time it runs before turning off.  I tried using the faucet in mechanical mode and it does not operate.  No water will come on in mechanical mode.  I tried just removing the batteries to turn it into a regular faucet, but it will not function.  Additionally, it has started leaking from the sprayer button.  Just constantly dripping while in use.  I wish I had never purchased this faucet.  My entire family hates it.
