It works well for tea bags or tea leaves. What's nice is that you can put boiling water into it and the temperature on the outside of the tumbler barely elevates in temperature. If you are on the go, and you are a tea drinker, just boil your water throw in a bag (don't need the infuser) or leaves (needs the infuser) and you're ready to go. It has 2 different lids: one w/ the infuser and one w/o (like a typical coffee lid) and then a cap (fits on both inserts) to seal in the heat. And in case you were wondering, it can be used equally well for coffee.
