Contigo

I used their "contact us" page to send a general inquiry and never got a reply (not even the automated one that the page says you will receive). I then used the Warranty Page and still didn't get a reply. Two days later, I contacted them via telephone. They claim they did get the claim information, but no photos were attached. (They require photos of your malfunctioning item). I had attached 2 photos to the original claim. After the phone call they just sent me an email to respond to with the photos attached. Even the email took a while to come through. I will see how the replacement goes, but I'm not very hopeful at this point. My advice -- buy mugs and water bottles from another manufacturer/distributor.
