If you are debating between this and a faucet with a separate sprayer and pot filler, this replaced one of those and this is much more convenient because that pot filler was usually in the way when I wanted to use the sprayer. Installation for this is much easier than my last one because you drop in the base holder from the top, not bottom, and tighten it from the top, not from under the sink. So the only under the sink work required is connecting lines to hot and cold supply. Seriously, unless you have money to burn, you would kick yourself for paying a plumber to install this if you stand there watching him if you are remotely capable of DIY. It comes with two allen wrenches, and you just need a Philips head screwdriver to tighten the base mount, then you put the whole faucet over that base and secure to the base with an allen screw. The only problems you might encounter with DIY is if you supply values are seized, which you can check beforehand, or if your existing supply lines somehow are frozen to your valve, but again you can check that easily with a wrench. When you turn this on, it defaults to full pour--you have to tap the button for spray. Once you toggle the button, it continues spraying or pouring until toggled again, so you don't have to hold it. When you pull it out of the box, the button may seem flimsy, but under pressure it works well. Under the sink, you add a counterweight to the tube, which allows it to retract fully. I have a large single basin farmhouse sink. You can pull the spray handle across and down literally to every corner. Unlike my prior sprayer, this one has a pivoting ball mount which allows you to tilt the handle to reach in any direction without needing to twist the hose. In fact, the reason why I bought this is because that twisting motion after 3 years broke the hose and started spraying water across the room. Thank goodness that happened within a minute of use and I was standing next to it, because it could have done that for hours. The on/off handle design is meant to be on the side. It moves 25 degrees away for hot and 65 degrees forward for cold. This works well for me because I happen to have a raised countertop directly behind the sink, and this asymmetry keeps the handle from bumping it. You could easily install the base 90 degrees to the left, so you turn left to right instead of front to back, but the hot/cold is reversed in that configuration. Also, in my under-counter configuration, the weight bumped into some lines. So the intended configuration is really better. Spray pressure is not quite as forceful as my last one. I mean maybe it is 95% of what I had. Still quite enough, but of course your experience depends on your water pressure supply. I did not see anything in the instructions that would allow me to remove/replace a fitting to alter pressure. Once tightened down, I see I may want to add some silicon caulk around the base because there is a slight gap which will collect crud over time. The base mount comes with a rubber seal to prevent water from leaking through your hole in the counter.
