I was just going to do my own experiment but turned it into a review. I bought the Contigo Mug at Canadian Tire and the wife bought me the Stanley from UFA here in Alberta. I like both of theses mugs but wanted to put both of them to the test. I remember my dad going to work and ALWAYS had a big Stanley thermos for his coffee. If you have a different brand of mug/thermos, let me know! I wouldn't mind checking it out!
