Ember's six-ounce self-heating mug drops to $32.99 at Woot

Ember's temperature-controlled mugs are typically pricey, but Woot is now selling the six-ounce Ember Cup in black for $32.99, down from $99.99, with a 90-day warranty through November 7. Shoppers can save an extra $20 on orders of $100 or more during Woot's Home and Kitchen Sale using code COOK. The smaller, handle-free cup suits espresso-based drinks and works well for refilling coffee, cocoa, or tea. Users set a drinking temperature between 120 and 145 degrees Fahrenheit through a companion app, and the cup holds it for up to 95 minutes on a charge, longer with the lid or on the charging dock. The cup is rated IPX7 for water resistance but must be hand-washed.
