Customer Ratings & Reviews

Everything works except the firmware update. I've worked with Ember support and completed all the normal steps like uninstalling & reinstalling the app, clearing cache & data, re-pairing the device. All that works fine. It's just the firmware update that continually fails, and Ember said this is a "Bluetooth Connectivity Problem" and are not covered under warranty. Their responses include: "Connectivity issues are not covered under our one year warranty and we can only offer troubleshooting tips. " and "If these troubleshooting recommendations do not work then there is nothing else that we can do as these issues are not covered under warranty." I asked how they determine this to be a "Bluetooth Connectivity Problem" and not a Mobile App or Firmware problem, and they simply restated their policy that states Connectivity is not covered under their warranty. I gave it a 2-star review because at the moment, the mug itself works fine. At some point, however, as their app gets updated, there's the real possibility that the normal operations, such as reading and setting the temperature, will no longer work with the mug due to the App - Firmware mismatch. This is a surprisingly poor customer service policy for an expensive coffee mug.

$129 for a cup seems pretentious and expensive, but I strongly recommend it, I almost never finish my coffee drinks when they get cold, but with this cup I enjoy it a lot more, I am getting another one for office I wish they make it a little cheaper though

The cup is small and it’s easy to use, but the battery life is not as long as I would like for it to be. Overall, it was a good purchase though for the cost.

Excellent - works as expected. Keeps coffee the desired temperature for as long as I need

Got this for my partner as a gift and he loves it. Keeps coffee hot and is nice looking on the desk when WFH. Can't be run through the dishwasher and they recommend not using a metal spoon inside, just minor adjustments to be aware of if you're coming from a non-smart mug.

Purchased for my wife and she loves it. It is Elasy to use and works as advertised. A teally great product for those who don't want their hot drink getting cold.

Great gift for elders! Can be a little hot but that’s as intended, good for reheating coffee/tea and still taste great

So far this has been a joy to use. No more trips to the microwave to keep uour coffee hot in the mornings! Thinking about getting a second one and already bought two more as presents.

Great cup to keep beverages hot and at your choice temperature. Lasts for over 4 hours off the charger. Sometimes it’s difficult to connect to your blue tooth. Other than that great coffee mug - love it! Would recommend

I bought this as a gift and she loves it. She keeps it at a decent temp and it lasts about an hour. For her that is perfect for others that may not be enough time.

If you're looking for a gift for coffee lovers, search no further. The mug keeps your coffee hot for a long while and looks super sleek/modern. Just don't use metal utensils to stir.

I like to size and look of this smart mug. Plan to use near charging source if plan to drink more than 2 cups away from charger, as it does not keep beverage heated for longer periods of time. Can definitely sip a couple cups casually.

Great mug. Love that it’s not hot on the outside but the drink is hot inside. It works great. I wish they made it a little bit bigger like 16 oz and somehow make it last a bit longer. But great concept and works very well. Coffee is hot till the last drop!

Love these mugs. I am spoiled by them now, it's so great having my tea at the perfect temperature all the time. Unfortunately, they are finicky and the charging coaster stops working after a while. Still worth it to me.

Let's be honest - the vast majority of people don't need anything like this and it's very expensive for a coffee mug. But I'd be lying if I said I didn't love having it. It's user friendly and just works. Come back an hour later and your coffee is still at that perfect temperature without the burnt flavor you get from other coffee warmers. I do wish it used a wireless charging solution to improve water resistance, and I think a 16-18 oz size would work better. (Note that while it's 14 oz, it's really more like 12 oz of usable space unless you fill it to the brim) It's also worth mentioning that the last few sips can sometimes get much hotter, but that's just because there is so little liquid left so any heat added will jump the temperature more. Not a big deal, but a minor annoyance.

It’s great! Keeps tea and coffee at a good drinking temperature. Not too hot, not too cold.

Love the color and works great. The battery does die pretty quickly though, but you can leave it on the charger as a coffee stand.

Does exactly how advertised. Keeps drinks warm. One downside is that the battery runs out quickly. Orher then that product is good.

Best bug, holds the charge really well. Minor flaw is: Bluetooth disconnects frequently

At the suggestion of my daughter, I got this for all my adult kids, myself, my sister, and my husband for Christmas. I would’ve considered it a frivolous purchase. It is not. It keeps your coffee nice and warm the whole time you don’t think you need it, but you do. The only thing I can’t speak of is how long it lasts. I also had to buy another charger and that was worth it too, just to have one upstairs and downstairs. Until you have one, you just don’t know. It’s like when the microwave came out.
