I got an Ember mug and use it every day and love it. It keeps my coffee at a set temperature (controllable via my phone over Bluetooth) so it doesn't get cold right away, and I can take my time drinking it. I've bought a couple more as gifts since, and the people I gave them to say they like them a lot. The impact on my life isn't anything to get excited about, but it's been positive nonetheless. I don't feel rushed when I drink my coffee anymore, and I'm able to concentrate on my work without that nagging "my coffee is getting cold" feeling.

I got a Stanley Beer Stein[0] from a sale 2 years ago or something. Th best thing ever. I put in ice + my favourite drink when my day starts and the ice is still there in the evening. Completely crazy performance for an open-topped container.

That sounds up my alley! What kind of material is the cup if that's the one you're using? I couldn't clearly tell from the website.

The mug part is metal, the electronics bit at the bottom is plastic-y rubber.
