Customer Ratings & Reviews

Family was thrilled with the gift! They said they looked nice too.

Gives a wonderful cup of coffee at perfect temperature

a total must have. keeps my coffee hot for long time.

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.

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...

Works as promised. Keeps the drink at the predetermined temperature.

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.

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

I LOVE my Ember mug, but this is the second one i have purchased and it has already lost battery power in less than a year and 2 months. I am 2 months out of warranty on this one. So $150 is a steep price for a mug that only works for 1 year.

Love my Ember Cup. Use it daily. It is so awesome! Makes my life so much better, and with a smile. It's a total pleasure, after reading or being on the computer for an hour, to reach over and have a cup of coffee, the perfect temperature! And this part is hard to believe but it tastes better when it's the perfect temperature, really! Did I mention I love my Ember.

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

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!

Was skeptical about this cup. I expected this to not work but was pleasantly surprised! Not only did it keep my coffee hot for 2 hours the cup itself never got hot! The cup has great weight. It’s not ceramic but has that perfect weight to it that makes it feel like it is. Absolutely love it. Want to get the travel mug now.

Easy to use and looks and works great. A tad on the spendy side however.

Love pretty much everything about this cup, I've used it every single day since I got it. The cup is built well, has a nice feel in your hands, I've never reached the end of the battery life, and the app is easy to use, though I only use the app rarely. Oh, and of course it keeps your coffee at the perfect temperature, which is what this product is all about.

Works very well! It is very convienient and stays warm

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.

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!

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

I bought this cup for my wife. She likes to take her time drinking her coffee and latte. She would usually have to microwave her cup two or three times to keep it hot. This cup does the trick! Keeps her coffee nice and hot, 145*, for hours! You can adjust the target temp to your preference but it tops out at 145. Great cup and has held up perfectly since purchase almost 6 months ago.
