Aquaphile Vacuum Insulated Coffee Travel Mug - Double Walled Reusable Tumbler Cups Light Blue 17 Fluid Ounces

These are nice quality tumblers. The threading for the top is really nice - even when the threads get wet the top screws in smoothly and easily. They are easy to clean because the mouth is wide. The outer grip has a nice feel in your hand. The bottom has a rubber mat on it so the mug won’t slide around. It keeps cold things very cold for hours. I use it more for cold stuff since I discovered this. I intended to use it for hot drinks only, but when I discovered how great it was for cold water, my thinking changed. As for hot drinks - it keeps them hot for a while. But not for a very long time. Even with the lid shut it cools considerably after 45 mins to an hour. This may be due to the size though. It holds more liquid than a standard coffee mug. And I am the type to only drink one cup of coffee. So I struggle to finish a full tumbler of coffee and the bottom is not hot by that time. I bought two of them - one red and one blue. I drink cold water from one and my coffee from the other. The best feature is the lid. Ease of screwing on and off and the fact it seals properly with no leaking. I recommend this item without reservation.

It's just the right size for my single Keurig coffee maker. I love the colors I order. Best cup to have for on the go or to just use at home without wasting my coffee. Glad I purchased them.
