The installation was relatively seamless.  We've never installed a faucet before and my husband and I were able to figure it out within an hour.  The hardest part was removing the old faucet.  The sprayer is really a lovely addition to our kitchen.  The spray feature has a good amount of power.  Only reason I wouldn't give it 5 starts is the sprayer is almost too powerful sometimes and sprays up to the countertop.  This can be corrected though by either pulling down the sprayer or reducing the water flow.
