This story is part of Mother's Day Gift Guide 2021. CNET editors round up the hottest gadgets for Mom this year.

"Now, where did I leave my coffee?" It doesn't matter. It's cold now. That's how fast it happens and it can happen to you unless you protect yourself with an Ember temperature control coffee mug, currently marked down by $60 to just $90 at Best Buy, for today only.

Travel from room to room and Skype to Zoom without losing a degree of warmth in your coffee, tea, chai, hot chocolate or hot toddy (no judgment). The Ember mug lets you create presets, so when the liquid reaches your ideal temperature, it'll keep it there indefinitely. Too hot or not hot enough? Easily rotate the dial control to change it on the fly. The Ember runs for two hours on a single charge or pop it back on the small, portable charging coaster so it'll run hot all day. (Psst, get ahead on your Mother's Day shopping and treat Mom to warm coffee she can enjoy for hours.)
