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.

I love this mug. I bought one first for my wife then ended up purchasing one for myself. When you get this mug, you will ask yourself why no one else thought of this idea in the past. It is a little pricey (I think the 14 oz should cost $99 at max).

My wife loves her cup, this is the second one that i have bought from Best Buy. She accidentally microwaved the first one (I strongly recommend you don't do this - lol). But the cups work great and the store was helpful.

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.

I got this as a replacement for a 10 oz mug I purchased 2 years ago. I always felt it was a little too small for my coffee consumption. It works a advertised, but since I take my coffee with milk, the heat makes it form a skin which is disagreeable, but not the fault of the mug. I have used this recently with tea (no milk) to get me out of a cold and it has been great at keeping the temperature hot enough to soothe my throat. Hope to buy a travel mug when they are on sale, those things are expensive!

Love this one of the best invention ever made use mine every nite

I've been on the fence with buying this cup since paying $150 for a heated mug was a bit much for me. But I ended up buying it on Black Friday for $99. First thing first with this mug, it feels cheap sadly. The bottom of the mug feels and looks like all their money went to that rather than building a mug that feels good. It is like they slapped a 99 cent plastic kids mug onto a heating disc. Second thing, the heat is 100% controlled via an app. Which is fine I suppose, but it would have been nice to be able to control it on the mug too, especially for this price. Next which is my biggest complaint is the misleading information for the mug, this mug is NOT 14oz at least not in the sense you can put 14oz of liquid in and be able to drink from it. 14oz is literally with the liquid on the verge of overflowing from the cup. You can put exactly 10oz of liquid in to be able to drink from it. Even 12oz is too much. Lastly overall thoughts and such....well unless you're sipping your coffee over 3hrs this mug is a novelty item. The travel mug one I can sort of understand the use. My advice is if you're wanting to throw $150 at something stupid, pick something else...literally anything else.

I wasn’t sure if I would actually use this but I use it everyday at work!! I set my temperature on the app & I don’t have to worry about my coffee getting cold!

Bought for my wife for Christmas. Safe had issues being able to connect it to her phone to change temps. Battery life is ok. Good besides connectivity issues. A little pricey.

I bought this for my Mother-in-law, and she LOVES it! She was always microwaving her coffee, and now she doesnt have to.

Great looking coffee mug however aside from looks, the functionality can be a bit better. Heads up for future purchases if for whatever reason you reset the mug by pressing the bottom button intentionally or unintentionally for more than 5 secs and see the colors flash.. that does mean it's reset the mug settings and you'll also need to manually reset your Bluetooth pairing from your mobile device (meaning forgot the device and then re-add as new device) in order for it be reconnected after reset and fluid detection to work. For the longest time I could not figure out how a filled coffee mug would read as empty. With that the battery life does struggle to lasr for my two hours of heated content sitting out on desk. So be prepared to have charger ready for charging if intended to keep intended temp for longer than that.

We owned the first Ember and upgraded to a bigger one (Ember 2). My wife uses this thing almost all day. Coffee that remains delicious all morning and evening Tea that remains hot. Defintely worth every penny if taste and quality of your drink are important to you. You don't have to rush to finish your drink in fear that it would go cold. A person who cannot control when their job or kids will need something should definitely consider getting one. Even after leaving for an hour or more, you come back to a delicious and hot drink.

I had never thought that a few degrees in the temperature would actually make my coffee or tea taste better. It does. You know when you make coffee, pour it into your mug and for a few minutes it is too hot, then for 2 to 3 minutes it is perfect and then too cold? Well, what if you could keep it always at that magic temperature that lasted 2 or 3 minutes? That is what Ember does for you. There are additional perks, it lets you know once the temperature is perfect, it can warm its contents even from ambient temperature if you want to and the materials are quite comfortable to interact with, they don’t change the taste of the beverage. We bought both the 14 and 10oz versions. The only difference aside from the color is that the 10oz heats up a bit faster, but that is it. Overall, if you’re constantly drinking something or going to meetings, this is the best mug to have.

I bought this as a birthday present for my adult son. He is a big tea drinker but always lets his tea go cold before he finishes it. He is absolutely thrilled with this cup, which keeps his tea at the perfect temperature until it’s gone!

The mug itself does a good job at keeping the drinks warm, the enamel paint is peeling off after around 6 months. Not sure if its worthwhile investing in another mug to see if this happens or not.

I purchased this mug for my techy bf's birthday. He LOVED it! I tried it later and loved it too. Long story short, we have 4 of these mugs now for home and our offices. Just make sure you hand wash it, and put it back on charger once it's completely dry. Also, don't use a metal spoon. We got silicon spoons to protect the mug.

Best Christmas gift to give anybody. I even have a temperature now I want my coffee now it’s 129 degrees lol. I love this

This cup is amazing. Its putside is cool to the touch, but when coffee is poured, remains at a hot temperature to your liking. Recommend the 14oz cup over the 10oz cup

I cant finally come back to my coffee after working and its still hot. The best part is that I can set the temp I want with my phone ahead of time to make sure I get the hot coffee I am expecting.

This was a gift and she loved it. The cup keep the coffee warm to her temp. The phone app. is really simple to use. Great buy
