But then we remembered two things: 1) how often we forget to freeze our water bottles ahead of time, and 2) that many re-usable water bottles aren't designed to have liquids frozen directly inside them. Plus, the ice cubes made in these trays can certainly be used to chill regular beverages as well!
Ultimately, we'd definitely pick a tray or two up if we saw them in a store or needed to round out an Amazon order (to get the free shipping, you know!).
