Customer Ratings & Reviews

I gifted this to my mom. The activation and usage is easy once I've set it up for her. All she has to do is press the wanted temp setting on her phone app and it'll start working. Time to heat to desired temperature is about 5-10 minutes. My only dislike is how fast the charge gets depleted and the constant need for charging.

I love this mug. So much so that when I saw it on sale I bought an extra one in the 14oz size for the house. It’s my go to for tea, coffee, and sometimes soup. I recommend finding a temperature you like and setting it there. Once that’s done you pretty much never need to use the app if you don’t want to.

I like the concept of this mug. Overall it has worked well, 9/10 times getting it right that there is a beverage in my cup. My I main complaint is thst i feel tied to the charger. 80 minutes goes by faster than you’s think.

Love this so much. No longer have to reheat cold coffee. Very easy to control, a great gift for coffee/tea drinkers.

This is my 3rd mug in about 6 years. I use them heavily so the battery starts to wear out after about 2 years. I've never had any problems with the app, although once I sync and set my preferences, I never use the app again. I don't understand why you would want or need to. I have found the Ember mugs to be exceptionally reliable and have recommended to many family and friends.

Awesome for someone who likes their coffee hot! Saving a lot of wear and tear on the microwave! If you drink coffee through the morning, it's best to use the recharging stand as a coaster, since the battery lasts about an hour and a half. Highly recommend.

The Ember Mug is a great gift for anyone anyone who enjoys their drinks to be hot, and to stay that way. They provide you with a nicely-sized cup which not only comes with an app to customize & set your own temperature, but it also has built in thermal technology to keep your hands safe & store all of the heat inside.

Works as advertised! Two recommendations: 1 needs longer lasting battery 2 or provide extra charging plate so you can charge in multiple locations.

Love having my coffee always the temp I want! I never have to top off the cup to keep it warm!

Love the mug, definitely keeps coffee hot. Not sure if my coffee maker is off or if this mug doesn’t actually hold 14oz. If I brew a 12oz cup it’s at the brim. Had it for a month and a half now with zero issues

This thing keeps my coffee at a perfect 140F for me. Only problem is if my phone is away from the mug it shuts off. Now i use this at my office job and sometimes i need to step away from my phone and need my phone. So when i walk away the mug and app disconnect and it shuts off. Its an annoying thing that just happens.

The Ember mugs are excellent. They perfectly solve the problem of trying to catch your hot drink during the short window of perfect drinkability before it gets too cool. Just set your preferred temperature using the app. It might take a while for you to learn through experimentation what your preferred temperature is, but one you know, you know. There are two sizes. My first size was the 10oz. mug. It is slightly too small to hold all of a Nespresso Virtuo coffee, and barely holds 10oz. from a Keurig. I was pleased when they launched this 14oz. size. It suits all my needs so I recommend paying the premium for the larger cup. My first cups where white. They tend to stain after some use. Therefore you might be more satisfied with a black or blue mug. Be careful with the charging base. The two little electrical elements that power the cup are fragile. Place the cup gently on the base. Don’t set it down too aggressively or you can break them. You can buy a new charging base but it isn’t cheap.

Great deal. Keeps coffee hot, ego high aside wife’s white one.

Bought for my mother in law as a gift. She loves her coffee scalding hot so she loves this cup. She could go take a shower and when she comes back to her coffee mug, the coffee is still hot! If you drink lots of coffee be sure to get the 14oz. It doesn’t look big so I can’t imagine how the 10oz compares.

Worked great for about 6 months! It started not charging the mug would only charge sometimes other times it would say charged then would just shut off.

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!!!

I never thought I needed this kind of mug. But it is amazing! Side tracked and forgot about your coffee? No problem. This mug keeps it warm and fresh, as though you just poured it. Easy to clean and love the color.

Like the title states, it is expensive for what it does, but it does what it is supposed to do well. App is easy to to use and the mug holds a charge well. Only cons is price, and isnt dishwasher safe.

It does what it claims to do. It keeps beverages at desired temperature.

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.
