Love, love, love
I love these and use them for coffee every morning. I bought 2 so I can rotate to last longer. They keep the coffee from staining my teeth. I have used them for 2 years now and was so happy to find them on Amazon. My two yr old one just broke recently so decided to get 2 to replace. Some don't work for hot so read description - this one does.
