This took only about 30 minutes to install. The technical part was a snap. The hard part was reaching around and between the plumbing.  Overall the install was a piece of cake.

Now on to the features: everything is working as it should after day one. Love the "wave on-wave off" feature, love the handle that locks in the spray mode and the pause button is pretty cool too. However, I've already disabled the "Ready Rinse" feature. I find that this feature, more often than not, turns on the water when you don't want it. Thankfully both features are easy to disable/enable as needed.

The only things I would change are very minor: I would have the faucet swivel through a slightly wider arc and I would add a little more heft to the hose retraction weight.  Despite these two nit-picky things I am completely satisfied.

I'll be back to let you know if the product starts to have problems.  For now, buy it.
