Customer Ratings & Reviews

Very easy to setup and use. Great for those who work at a desk and want to keep their drink at a desired temperature.

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?)

It’s a great mug.. everything good. The look .. . just size is a little small .. for the price ..

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.

Great cup, bought it for my wife she uses it everyday

I have always loved hot coffee and continually putting it in the microwave was just annoying and wrong. I received this mug as a gift and will never drink from a regular mug again! I set it to my degree of warmth and it STAYS hot to the very last sip. And I can carry it wherever I go inside or outside. Absolute genius product! I would advise getting the 14 oz size to leave room for creamer and less spillage.

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.

Very good rechargeable mug with temperature selection- works very very well! Charges in about 2 hours from dead, and keeps your beverages at the exact temperature you select when you link it to the APP.

Very cool item if you like to keep your coffee hot,

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)

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.

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.

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)

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

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).

A perfect product for keeping your drinks warm. I like my coffee hot and i drink it slowly. This keeps it hot. The weight of the cup is a bit heavy but its not that will bother you. Cleaning of this product is also very easy with no hassle.

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.

This cup is wonderful! It heats up perfectly, tells the temp of your drink then allows you to change the temp. If I had to say something bad, its only a 10oz. I see they now sell a 14 oz cup,I will be purchasing that one as well.
