Poorly insulated mug to the point that the built-in heater is actually worthless, extremely expensive for the poor results, a Thermos" brand keeps temperature a lot longer than this mug, too bad for such a cool travel mug
This is not an insulated mug; if that’s what you want, you will be disappointed. It reaches and maintains the desired temperature for coffee or tea. It is limited by the battery life, which is 2-3 hours. However, if you have a table-top charger and a car charger, you can keep your coffee warm all day.
Hey! I looked some of your videos and just followed you. Just wanted to say i loved the quality and simplicity of your videos. Keep up!
Thanks so much!

My none travel mug has be going strong for 4 years

That’s strange I’ve never had any issues in the three that I’ve owned and bought for friends
