So I got the delta touch 20 and it is spectacular. It has easy to you functions on the pull down sprayer. It also has this great feature with a spray guard functions that let you spray off your dishes with little spray back. Another cool thing is the led light that changes color with the temperature of the water. The light is blue for cold, red for hot, and purplish pink for in between. But the best function of this is the touch part. You can touch anywhere on the hot cold handle, the base or the neck and it will turn on the water to whatever you have it set it. It is simply amazing. It also has a manual turn on. Very glad I got it.
