I drink 10-16oz of coffee a day, and about 20oz of tea (obviously not all at once). This tumbler is great for either, and keeps the liquid hot for as long as I take to drink it.

The lid is not great. It’s held in place by friction, and just has a hole. Not great for commuting. I put the lid from another Aerial Resupply tumbler on, but the tab on that lid broke and so I am stuck with the non-sealable one for now.

This tumbler dents very easily. I dropped it from about 4 feet and now it doesn’t sit flat. Attempts to use a rubber mallet to flatten it failed, so now it’s just a bit goofy. Usable, but goofy. Undesirable for something containing very hot liquid.
