Looks and works fine so far; the installation guide needs improvement.
I received the Alternate version, which includes QuickConnect hoses and a Quick Connector, in addition to the traditional supply hoses (which we used). We also connected the QuickConnect hoses into the Quick Connector, and all is well, but the installation guide does not describe the purpose of the QuickConnect hoses. (Perhaps they are to connect to QuickConnect plumbing (which if that is a thing, we don't have), but the installation guide does not show that kind of connection, if that is the case). It would be useful to know the purpose. My guess is the QuickConnect hoses are terminated in the Quick Connector so water won't leak, when the sink is used.
In the installation guide, Section 3, there are two versions of the installing, but they are not marked. Perhaps they are then non-alternate, and then the alternate versions, as a continuation from section 2.
The sink came with both a "black seal (1)" (curved 'gasket'), shown in the non-aternative installation section, and a "black gasket (4)", shown in the alternative version. It is confusing to have both these parts. Perhaps the sinks come with both versions, even though you only need one of them, which is determined by the sink version.

Great product, arrived damaged.
I recently purchased and registered a new kitchen faucet and three bathroom faucets. All Delta, all beautiful. My issue is that on the second bathroom faucet installation, after removing all the existing plumbing, my plumber informed me that the threads coming out of the bottom of the new faucet were damaged and he was unable to install it, requiring him to re-install the original faucet and drain assembly. The new/damaged faucet was returned to Home Depot and a new one was purchased. Three days later my plumber arrived and installed the new assembly with no issue.
I was disappointed that I had to pay a plumber twice for the same installation, but, more importantly, I am disappointed in this quality issue as I expected more from Delta.

spill over ring did not match faucet color
I like the product, one start removed because while i got the faucet in gold, a spill over plug is nickel colored. It is visible, and to me this lacks attention to details. The reason I paid extra for the gold finish is that all other fixtures and handles in the bathroom are gold and a nickel colored ring really sticks out of place. Since the faucet was recently installed I cannot talk about its quality and longevity

Not a good purchase
The nozzle has given us continuous problems - from the moment it was installed, we've had to bring in a plumber multiple times. The toggle switch between spray and regular flow is faulty - it gets stuck in between -- causing it to emit a high pitched sound and spraying water everywhere.
Regular flow also regularly seems to be a problem - very little volume of water comes out until the nozzle is replaced, or some other fix which is usually only temporary until it happens again.
Also for the deep sink that we have this is simply too short a faucet - it splashes water all over the counter when we use. If we could replace it, we would choose something that is better made than this one. Its simply not good quality.

What are you supposed do with the quick connect lines when you have a conventional compression connection? Is this model available with only conventional connections (the one I received has BOTH)
Hi Valued Customer,
Thank you for your question regarding our Delta Faucet. Please accept our sincere apology for the inconvenience you are experiencing. We will be happy to assist you in resolving this issue as quickly as possible.
Follow these steps to install a compression fitting on PEX:
Cut the PEX tubing to the required length using a PEX cutter.
Slide the compression nut onto the tubing.
Insert the compression ring over the tube.
Push the tubing into the fitting until it stops.
Tighten the compression nut using a wrench.
