I just got one of these and am pretty happy with it. The folks at Naidre's all seem to like it too. I Am Not A Paper Cups are for sale in lots of online stores, but I found it cheapest at the mother of all internet markets, eBay. It's double walled like a thermos to stay extra warm, and the silicone lid is an extra nice touch. And side by side with a real cup--no diff!
