Customer Ratings & Reviews

Received the 14 ounce Ember mug as a gift. The battery goes from 100% charged to 5% in 10 minutes. It works great on the charger, but on Day 2 of use, I pull the mug from charging over night. The app says the battery is 100%. I make a cup of coffee from a Keurig pod, add cream, sit down on the couch, and within 10 minutes a message pops up saying its time to recharge. The Ember stops heating, and worse yet, the thin metal cup cools my coffee faster than a dumb mug! Again, it’s great when I sit at my desk with the cup resting on the charger, but never wander from the charger!

How can you justify spending so much on a mug? What’s wrong with us, are we brainwashed? Are we so lazy that we can’t even use the microwave to reheat our drinks anymore? We need help, we don’t need useless gadgets. The basic idea with this mug is outrageous. Battery holds power for about 45 minutes, I’m constantly recharging this thing, i have received it as a gift, it’s more of a gimmick

Purchased as a gift. Keeps coffee hot for almost three uses and only takes 2 hours to charge. Convenient to adjust the temperature from your phone. Will likely purchase the travel lid.

Product was great, worked as expected, customer service was awesome while picking up order.... 6 stars out of 5

I bought it in my trip to Walt Disney World, I’m from Argentina. It’s totally amazing!!! I love my ember mug!

I wish it came with a lid, luckily I had one that fits. I feel like it keeps my drinks warm for eaily 3-4 hrs

Keeps coffee at perfect temperature gor slow sipping. One charge will last enough time for approx 2 drinks.

the packaging was great and the products works well just wish i was able to make the temperature higher.

They make great gifts. I've bought several over the past year.

Had oroblems with the original purchase. Called support and was promised a new mug for no charge. Checked my account a few weeks later and found i had been charged $99 for mug only. Replacement mug worked three times. Nothing worked after that. Rarely charges. NEVER heats. Loses BT connection 99 times out of 100. When it DOES connect, it does not return to previous temp in spite of what support says. This Product is far from ready for retail and desperately needs new engineers and lots of testing. Until then, my advice is save your money and avoid the frustration and expense of a failed concept.

This is the 3rd time I’ve bought these mugs to give as gifts and it’s always well received!!

The first one we purchased holds the power so much longer than this one - not too happy that it drains quickly.

It works for a while. Then the battery doesn't last as long. Next, the charging coaster will stop working, likely from 1 of the two charging pins not springing back up to make contact with the cup. $40 just for a new charging coaster. $200 dollar cup into the garbage. Just get a good thermal mug. Save yourself some money.
