Customer Ratings & Reviews

Many hot beverages taste surprisingly different at even slightly different temperatures. This mug allows you to find your ideal temperature and it will keep it there for you. The iOS app needs work, but is functional if you can figure out the quirks. Overall I love this mug. If it becomes lost or stolen I will buy a new one immediately.

Great mug, works amazingly with the app to keep exactly the right temperature! Feels good and isn’t too heavy.

My wife loves this mug. The fact that it keeps her coffee warm has won her over. She wants a bigger one.

I got this cup for my wife for almost free. It popped up on the member sales of the month, and with the money I got back from using my Best Buy credit card from prior purchases only paid $10.

So it works fine without the app, but the app is required to increase the temperature. The reason i returned it is because the battery only lasts an hour or so. Unless you're able to set it on the charger in between sips, it doesnt stay hot long enough in my opinion. Its probably ok at an office desk, but just isn’t practical for couch drinking. Plus, you obviously can't microwave it so we inevitably end up transferring the drink to a different cup when the nattery dies.

Sometimes the app won't recognize the mug- have to go thru the pairing process again but, it does what it says it will do! I tend to forget my tea/coffee while working but now with this mug, that's an issue! (First world problems, amirite?)

The cup size is perfect. You can enjoy your hot coffee for a longer duration.

I really like my new Ember Mug. It keeps my coffee the perfect temperature and the app is easy to use.

Christmas Gift for wife that is working great! Very simple to use once you download the app that’s able to control your temp settings. Simple hand wash then place on charging dock when done. She loves it, perfect for when she is at work or weekend mornings!

For all intents and purposes it does what it claims to do well, keep coffee warm. I had to dock it one star because it’s not a flawless device. The app is mediocre and it’s unclear at times what the temperature your mug is set to heat to without the app. That’s my #1 issue - the reliance on the app. Some physical tools to increase/decrease the temperature on the mug itself would make this perfect. The other issue I noticed is no matter what type of coffee I make - pour over, espresso, latte, drip - after I’m finished drinking there is a pile of fine crystals about the size of a dime at the bottom of my cup. If I drink the same drinks in a regular mug that never happens. I can only assume the heating element is causing them to form, and it wouldn’t be an issue if they weren’t so unpleasant to accidentally drink.

Love how this mug keeps my coffee hot and is simply to set up

It’s great for morning coffee! It keeps it at the perfect temperature for me. I love it!

Very nice mom loved it and she says that she uses it daily

Have tried a couple of these for my wife (who is constantly microwaving her coffee keep it warm). This is the only one that has kept her from doing that - quality product (get what you pay for I guess - not cheap)

Great product. The only drawback is that it doesn’t charger on the charger while there is liquid in it. The charge also doesn’t last very long if you like your coffee as hot as the cup allows (145)

it does the job keep the coffee hot easy to set up

I really like this cup. Bought the 10 oz, perfect size. Sits on my end table. Great having a hot drink every night.

Amazing cup. It keeps my coffee hot for a long time!

Got this for my wife for Christmas, and now she is getting me one for my birthday. Awesome gift for someone who has to constantly reheat their same cup of coffee. Maintains temp, and easy to clean (hand wash).

Easy set up and use. The plate is a bit bulky in the way the cord is hard to handle. The app is incredibly easy to use and the cup reaches its designated temperature quickly which is nice. Wish that it would charge faster is my only gripe.
