Customer Ratings & Reviews

These are the greatest mugs, I’ve had one for a few years and decided to get another color. I’m a slow coffee/tea drinker and I love how the Ember mugs keeps it my perfect temperature.

Valentines Day gift and absolutely love it! I generally pour a cup of coffee at the beginning of a call and sip throughout. The problem is that it is always cold by the end of the call. This keeps it warm all day on the saucer and if I am away in a separate room, up to 1.5 hours off the saucer. Perfect for the busy executive schedule.

Got this for my mom and she loves it. She is a hot coffee drinker and she can nurse one cup of coffee for hours. This keeps her coffee warm all day. I bought this when it was on sale but I’d probably buy it at full price. I recommend this product. The app is pretty user friendly. My mom is in her 70s and has no problem using the app.

Just got this for my wife whos always busy and always lets her coffee get cold she loves it

Love, not having to reheat my tea in the microwave with this mug. Makes for a great gift also. I also love the bold color

Great Mug! Great design! Easy to use interface! Would highly recommend to anyone.

If you are a coffee drinker and love hot coffee, then this is the best device you can buy and it's well worth it. Be advised, this cup will only work with iPhone or iPad. Does not work worth a on Samsung Galaxy.

I thought this was going to be a pointless expense, but I love it since the first cup of coffee… I’m always easily distracted and by the time I want to finish my cup of coffee before, it was very cold… not with the ember, I gasp and smile, there it was, my cup of coffee, at the perfect temperature and totally worth it.

Absolutely love my Ember. I love having tea but often times never get to finish my cup before getting cold, now with the ember i never have to worry about it getting cold. More importantly can always have to perfect temperature for my drinks to really ensure full flavor.

Love the ember and the new color! I’ve had 2 before!

My Mother-In-Law is still thanking me for this super amazing coffee cup!

This was a great purchase. I normally drink my coffee from a Yeti to keep it warm but on the weekends I enjoying drinking from a mug. Temp control is perfect!

This is my second ember. I found the smaller size a bit too small since I use milk. I still use it while the bigger one is charging. I am very happy that my coffee stays hot while I do housework or am on the computer. Saves me multiple trips to the microwave and the Ember coffee flavor doesn't degrade as it might with the microwave.

I have bought two of these now and they work well. If you give to someone that uses the microwave to heat their coffee hide or unplug it. They will quickly burn the circuits and no longer work.

good tech with the mug, but wife hardly uses it. much easier to just microwave a mug she says

Great concept! But if you have a few sips of coffee left in the cup, it does tend to taste burnt, and it creates a strange film at the top of the liquid. BUT - If you have the mug more than 1/2 full and leave for 20 mins or so, the beverage does stay nice and hot when you get back...

Product looks great, size is perfect, and works so well.

I love this mug! It keeps my tea at the perfect temperature all afternoon! You can control the temperature you want it set at and it handles it from there! Highly recommend!

Great cup! Everything works well and is easy to use. My only complaint ( and it’s mine, not the manufacturer) is that the cup is too small! Should have bought the bigger one!!!

default temperature is 135 degrees. With the app, I upped temperature to 140 degrees. coffee is more enjoyable at my desired temperature. I did not think 5 degrees would be noticeable, but it is.
