Used for first time last Saturday, May 28, 2016. I have bought several mugs over the years and they usually only keep coffee hot for an hour or a little more. Ran hot tap water in mug, let it set for 5 minutes, microwaved coffee(my pot just keeps it pretty warm). I like it very hot. Put it in mug and went to work at 8am and started drinking some while it was still hot so I had to sip slowly. By 10am it was still very hot. So far so good. At noon it was still good and hot. By 2pm it was still hot and very tasty. At 2:30 I had some and it was still very good. I am extremely pleased because this was in an air conditioned room where temp was below 70 degrees. No doubt when hunting season comes this will provide excellent coffee for at least 5 hours on cold days. I have recommended this product to several friends so far and will continue to do so. Super easy clean up, also. Also, it fits my cup holders in my truck and car. Wish my regular Stanley thermos was of this quality.Read full review

They're really going somewhere with the design of the lid and button seal mechanism. When it's working well, it really is great. Simple to dissassemble for cleaning, and affirmative seal. It's natural to use, however, the button pops off and leaks from the same area. I'm going to see if I can figure out a hack to prevent it. Also, the way it narrows the cylinder at the top for ergonomics also sacrifices thermal insulation. I can feel the thinner area warm with hot coffee and can't seem to get the time it advertised for keeping it warm.

this vacuum mug solve my problem with my cooled down coffee. since i work on construction, outdoor most of the day, this mug keep my coffee warm since morning until night. the size also perfect to carry anywhere. easy to clean since we can take out all parts of the cap. heavy duty, we fell together hundreds times, and stand back up again together also, and still work perfectly. this mug just became my first buddy anytime anywhere.

This is an incredible product! Why? Because it keeps drinks cold for so long. I had the bottle full of ice sitting in a black car all day during a heatwave in Sydney Australia and found none of it had melted at the end of the day. It’s really easy to drink from - press the button and you can drink. Release the button and turn it upside down and no drips. The double walled product prevents condensation on the outside and it is very easy to clean.

Everything is great - doesn't leak, tea stays hot for a few hours (sometimes even too hot :) ). Great cup!
