Installation is pretty simple if you have lots of space under the sink and don't have an existing faucet that is stubborn and tough to backwards engineer the removal. Sadly, I had neither. But after I got the old faucet off it took maybe 30 minutes to install in total. (I had to stop partway through to look for a wrench) The toughest part is tightening the nut that secures the faucet to the sink. Even with a plumbers wrench I didn't have the room to tighten it down, I didn't have a giant wrench to snug it down so I ended up using a pair of large channel lock pliers. I just hope it holds because I mounted it with the deck plate since I have three holes, and there is a lot of free space between that and the sink itself. I mounted the spray head weight almost at the bend in the hose and I am hoping that it doesn't crimp the hose at the edges of the weight and cut off water flow. Time will tell.
Aside from the installation issues (obviously I am not a plumber, but I have done more than my share of plumbing around the house) I love the look, feel and simplicity of this one hole faucet. It's solid and quite heavy compared to other faucets. The height and depth of the faucet is perfect for my small double kitchen sink and I think it would work even better for a deeper sink. I suppose that's next on my wish list. I do love this faucet and am looking forward to years of use.
