I received my DaVinci faucet early March.
We installed it ourselves. It was pretty straight-forward [enough], since we had the right tools.
Build:
Compared to the previous faucet (a pretty decent Moen), the DaVinci looked and felt much more sturdy, solid, and higher quality.
The previous faucet was completely "open" on the bottom; that is, you could flip it over and see in insides of the faucet.
The DaVinci did not have this opening. It was completely sealed. The DaVinci was "virtually* a solid piece of metal (not literally, but once you see it, you'll understand).
The DaVinci didn't feel like it would break, nor did it seem like water would "get somewhere" either inside or underneath and cause unseen mildew or something.
Actual Use:
After a good month or so of use, I've found that while the fountain feature didn't "totally" transform my regimen/habits into the new age *chuckle*, it did make the usual tooth brushing more hygienic and "proper". *holding wine glass with pinky raised....sip*
I did get the 'chance' to rinse my eyes, which was indeed quicker and cleaner than using my hands.
I also noticed that I didn't have to turn the faucet handle a full 90-degrees in order to get adequate water pressure. I could get enough pressure from what seemed like a mere 25-degree twist of the handle. Considering that the max gpm on this thing is about 1.2, I figure I'm saving some water here as well.
Design/Look:
I got the Satin Nickel finish.
It looks really good. It has a subtle gold hue to it, which I like.
The size of the faucet is ...well, it has this elegant 'bulk' to it. It's not small, but not HUGE. Size-wise, it's the "Mercedes E-Class"...versus a small C-Class or the big S-Class.
You'll definitely be inspired to upgrade other fixtures and such in the bathroom once this thing shows up on the sink.
