It has been nearly four years since I purchased this faucet and after my recent interaction with Delta customer support, I felt I had to leave a review for it to explain why you should not hesitate to buy this faucet.I won't spend a lot of time getting into features that you can read about on the product page. The flow handle works smoothly and the RED->BLUE temperature indicator is very helpful for avoiding unpleasant surprises. The touch control works as expected (with a couple of exceptions I'll detail below). So far it works as well as it did the day I bought it.Due to some previous issues with my plumbing I elected to hire a professional plumber to come and install it for me so I can't say if it's easy to install. However I can say that the plumber was done in about 15 minutes and looked at me like I had wasted his time on something so simple, so there's that:)When I installed this, the plumber predicted that the electrical valve would succumb to calcification and stop working in about 9 months. Four years later I haven't lost any water pressure and I'm still using the original valve.I've had two interactions with Delta customer support for this faucet. The first time it seemed that the electrical valve (the one the plumber warned me about) had stopped working. This was about two years after I bought it. Delta shipped me a brand new valve, I swapped it in and it didn't work either. It turned out to be my mistake. The battery holder is much larger than it needs to be to hold the 6 AA batteries that power the valve so there's a sort of frame/spacer thing that you slot the batteries into before you place them into the holder. If you take the spacer out, the holder is the exact size for using C batteries instead of AA. C batteries are the same voltage as AA, just hold more charge so I figured I wouldn't have to change batteries out as often if I used C batteries instead. There's nothing in the manual about using C batteries, but it did work, but only for a couple of days. Not really sure what happened - maybe the weight of the C batteries bent the battery contact or something? From that point on, even putting in a fresh set of C batteries did no good - I even used a multimeter to test that the batteries were good. That's why I thought the valve was bad. When the new valve didn't work either, I swapped the AA batteries back in and suddenly everything worked perfectly again. Weird but I'll take it. I have the brand new replacement valve tucked away in case I ever need it, but as I said, it's still going strong after nearly 4 years.The only real problem I've had with this faucet is the magnet that holds the sprayer in place on the faucet neck. Touching the faucet neck with soaking wet hands, or submersing the whole sprayer head led to water getting trapped around the magnet in the faucet neck which caused it to rust. At about the 3 year mark the magnet disintegrated and fell out and the sprayer would no longer stay in place when retracted. I dealt with this for nearly a year before deciding to call Delta and see what they had to say about it. The person I spoke with on the phone was extremely helpful and conscientious - he even used a mobile tool that let me show him what I was seeing with my phone. He knew exactly what the problem was, gave me a procedure to do on my end and sent out a kit to replace the disintegrated magnet. In hindsight the disintegrating magnet was completely preventable had I know that it was important to keep that area of the faucet dry. (There's no reason it should get wet normally). When the kit arrived, it was a cinch to pull out the old magnet holder with the supplied tool and pop in a new magnet, now I'm back to good-as-new operation, and the faucet still shines up like the day I bought it. I'm super impressed with Delta's customer support.The only other quirk I've encountered with the faucet is almost a fun thing. The touch control works by measuring changes in capacitance - when you touch the faucet then pull away, the electrical field of your body interacts with the metal in the faucet to register a "tap". 99% of the time this works perfectly (unless the battery is getting low in the control valve), but every once in a while the faucet turns on when something else modifies the electrical field near the sink - such as opening the microwave door, lol. I'm also able to turn the sink off and on via remote by activating a 5W 2-way radio from a couple of feet away!Not to worry, if the sink is accidentally turned on, it will stop running after a certain number of minutes.In conclusion, this is a fantastic faucet and it has exceeded my expectations. It's not perfect but Delta support more than makes up for that.
