It took me 2 hr to remove the old faucet (opposite nuts, screws, washers, water lines through rings - you name it), and 15 min to install the new one (2 screws to mount the faucet and the 2 nuts to connect the water lines). If everything was this simple! 
And it looks and works great. I must say that when switching from stream to spray there is an increase in water pressure that may result in some splashing.  The handle can be placed on either side or centered for easy access.  Love it!
