Customer Ratings & Reviews

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.

As advertised keeps coffee at a specific temp that is flexible to what you want, easy to use. Downside is you cannot use regular silverware, it can scratch the coating. I use wooden stirrers and it works fine.

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.

My husband and I both have one. Mine is three years old now and his is one year old and they still work great and love them! I can sip on my coffee and it stays warm for almost 2 hours.

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 really enjoy that the mug keeps my coffee hot for nearly the entire length of tha battery life. The app was easy to pair with my phone and i love the ability to control the settings from the phone.

I haven't used anything else for my Chai Lattes since I got this mug. It keeps my latte warm all evening...no longer have to re-heat in the microwave when it gets too cool. Perfect for me! Might have to get another one for my regular and herbal teas!!!

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.

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.

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

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

Keeps your drink hot. I like that you're able to choose your perfect temperature. Given that I am a slow drinker, I wished the battery lasted a little longer. Overall happy with my purchase.

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

My wife’s loves this mug. It would be great if the battery lasted a little longer but fixed that by adding another base in the house. It’s great that anytime you go to get a drink of coffee it’s the right temp!

BestBuy Blue + Ember mug = Yes indeed !!! I use this everyday. Nothing feels a good as enjoying a consistently hot beverage during long drawn out Zoom meetings. Keep the coaster at your WFH workstation and you’ll never have to run to the microwave. ProTip(s): 1) Brew a carafe of coffee/tea and just top off your cup when you start running low. 2) The lid from Target’s $3 Room Essentials cup fits this perfectly! It keeps my tea cat hair free since my “co-worker” wants to lay on my keyboard all day LOL 3) Nix the app unless you want to be frustrated. Use it to set up your cup and preferred temp and forget it for daily use. Just check periodically for updates

Bought this mug for my wife who is a tea enthusiast and she loves it. Easy to use and does a great job with keeping the tea up to temp. Cool product!

[Employee of bestbuy] Sure this mug is costly but it’s worth it. I love how it keeps my coffee warm and saves me trips to the microwave to reheat my cup of joe. One important thing to note is that you cannot use a metal spoon to stir your coffee. This will damage the coating of the cup. A recommendation to the manufacturer is to clearly point this out in the instruction packet, and or put a disclaimer in the specifications to avoid future issues. Based on other reviews that point out the damage shows this was often missed.

I purchased the mug Feb 2022 for a Valentine’s Day present for my wife. She uses it every morning for her coffee and swears it has been the best thing ever! The only problem we have had with it is charging. You have to make sure it sits perfectly and wait for the flashing red to flash a couple of times. Besides that it still works just as well as the day we got it. If you take care of it and make sure it’s dry before setting on charger you will enjoy it!!!!

This mug is wonderful. Every cup of coffee stays at just the right temperature and the cup recharges quickly. Took one star off because it will not stay linked to the Ember app.
