Also this. I bought an
Ember coffee cup.
It's stupid really, but I can't help liking it. They're a hundred bucks. It charges and keeps my coffee at a perfect constant temperature, even after I remove it from the base and carry it around. How do I know? It tells me through the app.
Do I find it ridiculous? Yes. Am I glad I found it at Goodwill for $6.50? Even more yes.
I totally hate their whole mission statement from their website :
"Ember's patented technology allows you to experience precision temperature control in your everyday life, with the vision to transform how the world eats, drinks, and lives, empowering you to experience your world without limits."
It's a freaking cup of coffee, folks. Not a religion, for Pete's sake.
But I giggle every time I pick it up. I have changed the LED color to purple (because I can) and I'm playing with different temperatures, but the 136º seems to be a good start. There are five built in presets and room for more.
