A game changer for hot beverages
We purchased this T3 self heating Travel Mug a few weeks ago. This is a really great product and is exceptionally well made. It maintains temperature levels especially well. The materials are lightweight and comfortable to hold. The wall of the mug is thin and the outside of the cup doesn’t get hot. With the phone app you can set almost an exact temperature.We also have the smaller cups from Kepwam and they are great. It is great to have coffee that can stay hot or warm for hours. No more trips back and forth to the microwave to reheat your beverage.We can highly recommended these great inventions.Great feel, size, battery life and colors.

Does it really work.
This works exactly as described. It is a bit pricey but I have tried several other brands and this one is the first one that actually works.

Keeps coffee hot
Got it for my fiancé. He likes his coffee kept warm, and at the highest temperature it keeps it perfectly hot for long enough. It’s been a couple months and it’s not used everyday so no idea how long it lasts but does what it says. It’s easy to use with your phone. It holds battery well as long as you aren’t reheating things in it. The design is nice giving you the option of a straw or sip, and also has a carrying handle on the lid. Easy to clean. If there was a bigger model would be great but it works.

Save your money
It worked the first time I used it then not again. A replacement had to be fought for. And that one barely works. The battery life is horrible. It takes forever to warm up if it feels like working. This costs wayyyyyyy too much money to be so unreliable.

Great product, just needs some tweaks
I got this for my husband and he loves it! The only problem was that it doesn't come with a vent hole, which means it gets airlock. My husband is very handy so he just drilled a little hole (3/32") and now it works perfectly! He did say it would be nice if the charger fit in the cupholder in our vehicle so he could charge it while we drive but it does stay charged most all day (longer than we spend in the car driving!) so he's able to keep his coffee nice and hot. It holds a charge well when not in use so it's good-to-go when he needs it. And it charges in a few hours. My husband is NOT techie and figured out how to use it without grumbling so it must not be difficult at all, haha! It is kind of expensive but he said he would buy it again so I assume that means it's worth what we paid! Oh, it would be nice if it had a handle...

Easy to use and drink with
Nice easy to use. Last a good amount of time. Expensive but better quality than others I have tried. Drink stays warm for longer. Easy to figure out how to use the functions.

Sturdy travel mug but disappointing battery life
Sturdy build. Keeps my coffee warm like an insulated mug should, even with the heat plate off. The interior is stainless steel, so you don't have to worry about suspicious coatings leaching into your hot beverage. I'm a little disappointed in the battery life. It only lasts about 3-4 hours so I have to charge it daily. On the highest setting, the coffee is a perfect temperature.
