We use these cups for our church services on Sundays. We're happy to use them not only because they are eco friendly, but also because they are very affordable. The only downside is if you want hot tea, you either need a cozy or another cup underneath because the cup gets VERY hot. I would buy cozies but I think it's a waste of money, and they are almost as much as the cost of these cups. Not to mention not eco friendly if everyone uses them for each drink.
