Customer Ratings & Reviews

Pros: Mug - Sets and holds the temperature of hot liquids really well. I set my coffee for 126F (52c) and it's at a good drinking temperature without getting colder. Good for all day sipping. - The mug doesn't get too hot. It'll get warm but definitely no where what I would expect. - The handle feels nice and I can slip 3 fingers in there. The edge is sharp but definitely not something to worry about and adds a bit of class to the presentation. I like the handle. - The mug fits perfectly on the coaster so there's no guessing where it needs to be placed to charge.

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!

Easy to hold, maintains perfect temperature for 3 hours with the Ember lid accessory.

I love this cup, my drinks stay at whatever temperature I set for the entire cup down to the last drop!!! This is an excellent gift idea for anyone.

I love this mug. I bought one first for my wife then ended up purchasing one for myself. When you get this mug, you will ask yourself why no one else thought of this idea in the past. It is a little pricey (I think the 14 oz should cost $99 at max).

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.

This is the 5th Ember mug I have purchased, with three of them as gifts. They have all been a hit as gifts and I personally love using mine every day. I am a verrrryyy slow coffee drinker but this keeps your coffee or tea at the perfect temp. It may not heat up liquid from cold, but it will heat up lukewarm liquids to the perfect temperature.

Decent cup. Works as advertised. Battery depletes fast when in use however.

This is our fourth ember mug in our collection and we use them daily. The battery lasts a decent amount and being able to set the exact temperature really puts the icing on the cake.

They loved it, easy to use with only one downside of not being dishwasher safe which is expected.

I was gifted the Ember mug at work and I love it. My coffee and tea are always hot. Its easy to use too.

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.

Excellent piece of technology. I use mine everyday. The battery doesn’t last too long, maybe 2-3 hrs off the charger. But does what it needs to do and satisfying at that. Works well and very simple.

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

I would give it a better Star rating if the battery lasted longer. And the inside finnish didnt syart to peel already. The adjustment capabilities are truly exceptional. Temperature control is perfect for tea and coffe connoisseurs. I perchased one for myself and my wife. Even bought a travel mug. Mynonly real complain is the short battery life.

Love this cup Sometimes the charger has worn out but they sell replacement chargers. Only drink my coffee with that mig

I really like the cup. However, unless you purchase the lid that goes with it, you’re gonna constantly have a film on top of your coffee. Also, the cup doesn’t stay fully charged even when on the charger maybe 80%. but most importantly, it keeps my coffee, hot all day.

My wife loves it! She drinks her coffee slowly and it stays warm!

Ordered the blue Ember mug online. Shipping only took a couple days. It works well. The app is easy to use. Having hot coffee or tea from start to finish is fantastic!

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.
