Vacuum mug "Travel Mug" 12.2 fl .oz. in blue, Blue

I bought this product 4 years ago, and have used it daily (approx. 250 days a year) since then. It has accompanied me on my daily commutes, living either in the cupholder in my car (winters), or kicking around the pannier on my motorcycle the other 9 months of the year. It's still going strong. I've dropped it more than a few times, and it has a couple dents to show for it, but that has not hurt performance. One thing I did do was to re-glue the rubber on the bottom. I really like the lid closure and the non-directional nature of the top. The top also comes apart easily for cleaning, a plus. When closed, it does not leak, even when laying down, other than a couple drops that may have been trapped above the seal. If I had to replace this mug, I would certainly replace it with the same product. Update 2023-05-09: I've now been using this mug daily for 6.5 years, and it is still going strong. It continues to accumulate dings from use, and continues to perform flawlessly.

There is something about the engineering of this design that puts it way above all the others on the market. You put in your drink. You screw on the top. It is not going to spill in the car or in your purse. When you want a sip, you just press the round button in the lid. When you are done, just unpress the button. It pops back up and seals the container. Easily washable, very high quality.

This is a sturdy travel coffee mug that keeps it warm for hours. Heavy and heavy duty.

Satisfied. Keeps cold and hot.

Work well when drinking from it. Keeps coffee hot for 3 hours warm for 4 hours.

Simply the best coffee mug ever.
