The endorsement
Kohler kitchen and bath products, particularly their Sterling shower door customer service. A roller on one of our shower doors disintegrated the other week. We didn't install the door and have no idea who actually made it, but a trip to Home Depot led me to believe it was a Sterling door of indeterminate model. Even though I had very sketchy information, and am still not sure if I even *am* one their customers, they're mailing us some replacement rollers free. Rawk.
