My son-in-law installed this for me today.  The instructions were very clear and installation was not complicated. One note... in my case the hose fittings were different size from the pipes. It took a trip to the local hardware store to find an adapter that had one end the larger size and the other end the smaller. Once that was found the rest of the installation went fast. 
I love the look and the functionality of this faucet. The fact that I was able to get the hands free operation using a battery pack was the best part because you get the functionality without needing an electrician to do the wiring. I am definitely glad this is the faucet I chose.
