I purchased a Contigo Mug June 2, 2009. Its a great looking mug and well made. Only one problem. When filled with hot coffee if tilted it not only leaks it sprays. This thing is a lethal weapon. I contacted Contigo who advised that my mug was defective and provided an address where I could return it for a replacement. I returned the mug. However they never sent its replacement. I have sent them several emails with no response. I have since contacted American Express and contested the charge.
So don't purchase from Contigo. They are not to be trusted. Once Contigo has your money you no longer exist.
