This is an update to the first review I left when the sensor on the faucet would not work. Dalmo reached out to me and sent me some troubleshooting tips and after making sure everything was set right and purchasing new batteries,my sensor now works! I am very very please with this product and how the seller worked to resolve my issue. Also happy this product comes with a 5 year manufacturer warranty! I am very glad I purchased this product rather than one twice it's price! 5 stars all the way!!

Received my faucet this afternoon and carefully followed all instructions for installing it. I will say the faucet looks great and has the functions of a high quality/cost faucet however the sensor will not work at all. I have emailed dalmo and am waiting to hear back. As a regular faucet I would give it 5 starts but since my sensor isnt working and I am still waiting to hear back from the company I will go with 2 stars. If they get back with me and we are able to resolve the issue I would definitely give this product a higher rating.

I was skeptical of a low cost faucet from a brand I never heard of but I am even more tired of spending 2-3 times the price for the big name brand that the last 2 I've had needed replaced after only a few years. Anybody remember when quality mattered? Anyway, I decided to take a chance on this cheaper alturnative and I'm glad I did. The appearance and finish is very nice and the construction is very similar to the Delta faucet it replaced. I'm no expert but the quality seems at least as good name brands, maybe better and if it lasts at least as long as the one it replaced I'll be happy.Installation was the same as any other faucet. No easier or harder. The supply lines were shorter that faucet it replaced and just barely long enough to reach the shutoff which is in a typical location. I would have liked them to have been just a little longer.  The control module for the sensor contains a battery holder that fits inside the module and is hardwired to it with a short wire. This makes battery changes cumbersome because the module needs to be mounted to rear wall of the sink cabinet. The manufacturer should consider either a standalone battery holder connected to the module with a long wire or some other improvement to make batteries more easily accessible and changes easier. One other concern is with design. The mixing valve handle location is on the right hand side which is common to many faucets of this type. In my 3 hole countertop configuration I had a soap dispenser in the hole to the right of the faucet hole which obstructed the side mount handle requiring the dispenser to be removed and a plug put in the hole. If the valve were mounted higher on the faucet trunk or if the faucet were engineered so the handle could be on either side it would be less likely to interfere with anything beside it. 
As for functionality, It is so nice to be able to start/stop the water hands free and to have the water flow automatically when using the sprayer. This is the first sensor faucet I have had and I think I'll find it difficult to ever go back to a manual control faucet. Most of the faucet failures I have experienced in the past involved leaking so I'm hopeful this one will last longer since the sensor activation greatly reduces the wear and tear on the mixing valve.
Most of the complaints I've read seem to have to do with sensor functionality. I had no problems once I understood how it was supposed to work but I will say I think if the included instructions were clearer and showed greater detail some of these issues might have been avoided.Time will tell but for now this seems like a good product at a great price. As mentioned I think there are some things that can be improved on in future iterations of the product but even as it I would still highly recommend.

Install took about 2 hr , which included removal of a 9 year old D*LTA faucet that grrr! wouldn't rotate anymore. The first thing the wife said is: "I liked the chrome finish on the old one". Oops. Remember to check with the boss. Then she says: "To turn it on (initially) you have to do 2 things instead of 1. Wave your hand in front of the sensor AND then move the handle." Sigh.

So far I like it a lot. The short pull out nozzle will take some getting used to, but I think the sensor is pretty cool! The auto ON feature when pulling out the nozzle is not that useful for me, as usually I do this to fill a pot or pitcher with water, sitting next to the sink, so it splashes everywhere.

Update: my wife told me that the button on the nozzle pauses the stream, so I am using that now. After 3 months, I notice that the stream or spray selector "leaks", but I suppose I can live with it. Also, now I wave my hand in front of ALL the faucets!
