Customer Ratings & Reviews

We originally went for the less expensive 10oz, but don't, it's too small. The 14oz is just about right. Once everything is synced up with your phone this little guy works like a champ. Literally will stay at the exact temperature you set it up. It will increase the temperature up to a higher temp if need be. Exceeded my expectations.

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

Gave the Ember-Temperature Control Smart Mug-14 oz to my son for a birthday gift. He loves that it keeps his coffee at just the right temperature, due to covid he's working from home and he keeps his house pretty cold in the winter. The Mug makes a perfect gift for a techy coffee aficionado.

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.

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.

Amazing mug. It’s great to have a hot beverage next to me without need to microwave it after sitting for a while. I like that I can set the temperature to what I like and it maintains it for me. Overall, it’s a great mug but a bit pricey.

I purchased one mug as a Christmas gift for my partner and one for myself. We both love these mugs! The app is very easy to use. The mug is nice to hold; feels good in hand. Finally, our after-dinner tea is held at the right temperature while we watch TV. I highly recommend this product. A suggestion: by the 14 ounce size.

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

Great! Excellent quality and love the blue color. Would be even better if battery lasted a little longer.

I cant finally come back to my coffee after working and its still hot. The best part is that I can set the temp I want with my phone ahead of time to make sure I get the hot coffee I am expecting.

Got this for my wife as a mother's day gift. She has a habit of leaving lukewarm tea all over the house. She loves it and it prevents her from nuking her tea in the microwave every 30 minutes.

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.

$129 for a cup seems pretentious and expensive, but I strongly recommend it, I almost never finish my coffee drinks when they get cold, but with this cup I enjoy it a lot more, I am getting another one for office I wish they make it a little cheaper though

Very elegant and easy to use mug. Only minor complaint is that I wish the battery would last a little longer. I set my coffee at 137 and it keeps it hot for over an hour off the charging base.

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

Love it. Easy to keep clean and the dark color doesn't show stains.

Got this for my partner as a gift and he loves it. Keeps coffee hot and is nice looking on the desk when WFH. Can't be run through the dishwasher and they recommend not using a metal spoon inside, just minor adjustments to be aware of if you're coming from a non-smart mug.

If you or a loved one are a hot beverage drinker, this is the best gift ever. I know, you are probably thinking...$150 for a mug is insane. But it's an indescribable joy. Hot coffee. For the whole cup. And for those of you who say you don't have this problem, you probably do and don't even realize it. Because this is piping hot, the whole time. Not just kind of lukewarm when you get to the bottom of the cup. Your last sip is just as good as the first. It's a great gift. It's expensive, but it's a luxury that I don't regret having in my life.

The cup is small and it’s easy to use, but the battery life is not as long as I would like for it to be. Overall, it was a good purchase though for the cost.

I bought this as a birthday present for my adult son. He is a big tea drinker but always lets his tea go cold before he finishes it. He is absolutely thrilled with this cup, which keeps his tea at the perfect temperature until it’s gone!
