I have installed many faucets, before this one all required uncomfortable positions underneath the sink with difficult access to the nuts and connections.  Installing this one was done from above, install the very clever attachment point, then position the faucet over it, turn it a quarter turn and tighten the set screw.  Water lines already connected to faucet didn't require reaching up to them and guaranteed no leaks!  High quality braided lines are long enough to reach the valves

Pros: Ease of installation (< 5 minutes), great look and function
Cons: A large piece of metal from the manufacturing process was still inside
