Ember Mug Sale: Take $50 off This Self-Heating Coffee Mug

If you’ve ever complained about your steaming cup of coffee going cold before you’re even a few sips in, something tells us you’re going to love this Ember Mug sale. The Ember Mug—if you’ve somehow missed its numerous placements on our gift guide list, is already on its second generation of mugs—but has made a name for itself by cornering the marketing on self-heating technology. Ever microwaved the same cup of mug of tea or coffee over and over and over again before it’s finished? No longer. Sir, we’re in the 21st century and we drink from smart mugs now.

Ember’s mugs keeps your beverages hot at the exact temperature of your choosing, between 120 and 145 degrees Fahrenheit, for up to 80 minutes. At $150, it might seem like a bit of a splurge, but think about all the wasted coffee that’s passed its prime (or curdled) over a span of a few hours while it waits for you to remember to drink it. Thanks to this sale at Best Buy that we peeped, the Ember mug is on sale for a much more wallet-friendly $100—meaning it’s primed for you to snap one up ahead of winter, or to bag a handful of ’em for the whole family as holiday gifts.

Just a couple of safety notices: Don’t put this thing in the dishwasher, and certainly do not microwave it—though with its self-heating capabilities, there’s really no reason to nuke it. The Mug comes in a range of colors, but for this deal, only the navy option is discounted.
