Really works
07/04/2019 by Meredith
This mug really does cool down your beverage to the right temperature and keep it there for a long time. I have one at home, and am probably going to get another for the office! It is also very sleek and sturdy. It is a little heavier than I might want in a travel mug since I take public transportation and also walk after work, so I would be carrying it around a lot.

This travel mug is amazing. It really does what it says it does. You pour the hot coffee into the mug, wait 2 minutes, shake, and it is ready at the PERFECT drinkable temperature and it holds it at that temperature for hours. No more waiting to drink your coffee when you are in a hurry to get to work and you won't burn yourself. I even use it at home when I want to drink out of a cute coffee cup. I pour the freshly hot coffee into the mug, wait 2 minutes and then pour it into my cute coffee cup. I love it. Buy it! It WORKS!

I haven’t used this as I only drink hot drinks in the winter. However, it is very heavy.
Not impressed butvdisappointed

I have followed the instructions carefully and am not impressed. It MIGHT keep a beverage a little warmer than most travel mugs, but certainly NOT worth the extra money. VERY disappointed as this was a Mother's Day gift for my vwife.
Mug is small and heavy

Temperature-Controlled Travel Mug

Every sip of coffee is a good one with a temperature-controlled travel mug. It’s made with phase change material and double-walled stainless steel to cool piping hot coffee (or tea) down to an ideal 140 degrees Fahrenheit in about two minutes and maintain the temperature for up to five hours. The spill- and leak-proof lid has a 20-degree slope for easier, one-handed sipping, too.


As a grad student, Thero vacuum-insulated mug Maker Chloris Yang was frustrated with burning her mouth on too-hot coffee and then, inevitably, ending up with too-cold coffee after letting it cool off for too long. Chloris put her book-smarts to use to create a solution that prevents both of those unsavory scenarios.

Thero cools scalding hot coffee down to an ideal 140 degrees Fahrenheit in under two minutes and keeps it there for up to five hours. Science is doing the temperature-controlling work here, thanks to phase change material (also known as PCM) sealed inside double-walled stainless steel. It quickly absorbs heat from the coffee and slowly releases it back to maintain that magical temperature.

Chloris put thought into the design of the lid, too, and made it spill- and leak-proof, and easy to use with one hand. So every sip can be a perfect one.
