Customer Ratings & Reviews

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

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

Excellent product. My second ember product that I absolutely lovez

My Ember mug stopped charging and working after about 12 months. Luckily, I had Total Best Buy Protection, which replaced the product. The only surprise was a $29 deductible, I didn’t realize that was part of the plan. In hindsight, I might’ve tried the manufacturer’s warranty first, since that would’ve likely been free. Still, the replacement process at Best Buy was quick and hassle-free, and paying $29 was much better than buying a new mug at full price.

Very usefull but a bit expensive. I enjoy drink at golden temptature while I am playing video game. I don’t have to worry about my drink getting cold.

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!!!!

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.

[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.

Perfect for keeping your coffee warm while at the office or home.

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!

This product does really keep the coffee hotter for a long time. It really works.

These mugs are great and do what they say they'll do. App is easy to use. Just make sure you don't leave it partially full, it'll keep working and the coffee with cook to the surface. Fortunately it's fairly easy to clean, but with the automated on/off, even if you turn it off, it seems to sense the liquid in there and turn itself back on. Just dump it out every time and you're good.

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

Haven't used it much yet, but its been great for teas. I tend to take my time drinking my tea and it's usually cold by the end. This fixed that issue.

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 have bought two of these now and they work well. If you give to someone that uses the microwave to heat their coffee hide or unplug it. They will quickly burn the circuits and no longer work.

Liked that it keept coffee warm . More efficant battery would be great .

Got it for my wife for Christmas. She absolutely loves it and uses it every day. The only major problem I see with it is that we are buying more coffee now because she's drinking more and in this economy it's rough. Taxation is theft and the government doesn't care about us. What's even more absurd than this inflation is how they want us all to be in electric vehicles by 2035?! Yeah okay pal that's gonna happen. But anyway great cup!

Keeps my coffee piping hot all day. Note, the rechargeable battery is not replaceable and lasts around 2 years, then the whole thing is trash. That's why 4 stars instead of 5.
