Perhaps the best feature is the lack of restriction in the entire design- I have an old well with very little pressure, and had just become used to not having much spray power at the kitchen sink. With this unit, I have at least twice the power of both flow and spray! Takes a few days to get used to the locking and release mechanism. Extremely well built and solid. Replaces a pull out nozzle for me, and I like this system much better - the under-sink area was so crowded, the pull-out was always getting hung up and tangled. There is enough hose to reach the entire sink area - but not enough to reach to the stove. It is a joy to look at and use every day, and the quality seems far superior to other faucets in the same price range.
