The Ember Mug is on sale at Amazon

My mom and I are both avid coffee drinkers with the same problem: We often

My mom and I are both avid coffee drinkers with the same problem: We often forget to finish our cups. We get distracted easily, so by the time mom finishes her morning routine, the coffee she painstakingly brewed right when she woke up is cold, congealed and just kind of sad. After trying — and not loving — several mug warmers, I decided to splurge on one designed to keep beverages the perfect temperature for hours: the Ember Mug, on sale right now. After using it for a year, I loved mine so much I had to get mom one, too — and she's now stopped drinking out of any other mug in her house.

It's the ultimate Mother's Day gift for coffee- or tea-loving moms, and it's marked down to just $100 (from $130), in both the black and white versions. A No. 1 Amazon bestseller, it's amassed over 5,700 5-star reviews.

The Ember is so much more than a basic mug. Once you pour in your hot drink of choice, you can set your preferred temperature via the user-friendly app. The app will notify you once the drink reaches that temp, and it will automatically adjust once your drink starts cooling. Don't have your phone nearby? The mug will remember your last-used temperature, and automatically warm or cool your drink so it can reach it. No need to turn it on, either: It'll wake up once it detects movement or liquid. It goes to sleep after two hours of inactivity, so it won't keep heating the liquid inside.

The temperature isn't the only thing you can customize. Just log in to the app, and change the base LED light to your favorite color. It'll also inform you when the mug is heating or cooling, and when the battery is running low. To charge it, just place it on the included coaster. The cup itself is scratch-free, and stays cool even if you have a hot drink inside. She'll never have to microwave her lukewarm coffee again!

No need to burden mom with special cleaning tactics: It can easily be washed by hand and used over and over.

"I was on the fence with this mug for YEARS!" shared one former skeptic. "Glad I FINALLY pulled the trigger and purchased! Having your last sip of coffee as hot as your first is a new thing for me now that I have this mug!"

Another shopper noted: "This mug is the best one that I’ve ever had! I can't believe how I can have a constant cup of hot coffee. Easy to set up for yourself and even better to gift to a friend!!"

A third shopper put it best: "Having my coffee stay the perfect temp through the crossword, sudoku and reading the paper! It's a dream come true!"
