“Ordered the wrong part for a faucet, texted them about and pictures of what I needed, they let me do a refund and they didn’t have the exact part but sent me a link to Kohler who did have it. They’re so helpful, I’ll totally order from them again. I’ll probably text first next time so I get the right thing in the first place :) ”

“After trying all over my area, I couldn't find the part for the faucet in my older house. The part I needed was found on the first try on their website and ordering was very easy. It was after hours, but someone responded to my text right away. The part was shipped the next business day. After putting the new part in the faucet works better than it has for years! ”
