Query: Good looker but a leaker and design flaws

Installed this faucet in October of 2012. Since then the o-rings have already failed. My wife loves to use a swivel type sprayer that threads into the faucet. You know the type. They can be purchased at Lowes, Home Depot, Ace, Menards. Just unscrew the existing aerator and screw a swivel type spray aerator in its place. Just one thing... the back pressure just from a new aerator causes the faucet to leak a lot of water at the base of the faucet. A Kohler representative informed me this problem can be expected and only the aerator that comes with this faucet is advised to be used. To be fair, Kohler stands behind their products. Great parts replacement policy in their warranty. Problem isn't the warranty, it's the design of the product. I would advise anyone to steer clear of of this faucet and look at another manufacture with a better engineered product. Hope this helps someone.
