Customer Ratings & Reviews

Love this cup! However, I had to purchase an additional charger to keep at work. The battery life is ok if you are a 1-2 cup coffee drinker. Which I am, before I even get on the road to work but by the time I get to work my coffee is cold. After I purchased the additional charger, I would say this cup is a game changer.

App for the cellphone has been updated from the original app that I got a couple of years ago. The new app works much better in regulating the mugs. This my second mug because I liked how well the first mug worked. Both mugs are working great.

Cool Idea, Got this for my Wife and she loves it. Keeps her Tea warm for hours.

This mug keeps my coffee warm and easy to wash. Highly recommend purchasing the larger sized cup.

I was feeling ridiculous about buying a temperature controlled mug; turns out it was just what I wanted.

Great product. Wife uses it daily and no more cold coffee! Super easy to use.

Nice product. Keeps coffee hot as advertised. I thought the battery would last longer though. It only lasts an hour, maybe a bit longer. Overall I am happy with the product.

So far so good. Wish the maximum temperature could be set to 155 as 145 is just about warm for my taste. I was debating between 10 and 14 oz due to additional cost. But ended up going for 14 oz and glad that I did. 10 oz would have been too small and require frequent refill. You might as well heat in the microwave on refill visit. 14 oz also carries perfect amount of heft and feel. You know you are holding something good with or without your tea or cofee. That said, be careful while washing (handwash only) as the contact points (the two circular rings) with charging coaster are visible and exposed.

Perfect size and keeps my coffee hot while im in meetings.

Nice size. Attractive. Works well. But it is yet another electronic and luxury device. It requires careful cleaning and handling (no dishwasher, avoid getting bottom wet), and electricity. It is not for everyone. There are other ways to prevent cold coffee. That said, I use it every day.

Love the blue color, the matte finish and the larger 14 oz size. Keeps my morning coffee perfectly hot which is the only way I like to drink it.

Keeps coffee at the correct temperature. Battery life is a bit shorter than desired, but if on the charger it works for multiple cups throughout the day. Good investment.

It's a completely unnecessary product and far more expensive than it's worth, but still, I use it every day and love it. It takes me a while to get through my daily hot beverage and either poured out the last bit or just took a big swig to finish off the cold remains...but with this my drink stays the exact temperature I want down to the last drop. The 14oz is a little inconsistent in the temperature sometimes...the bottom of the cup can have the liquid a higher temperature than the top depending on how long your drink has been sitting. It's a big mug and exposure at the top since it isn't sealed seems right.

Works as advertised,but I’ve been having issues with pairing on phone but it’s ok so long as it’s does if main function keep coffee hot ,I would recommend I wast less coffee and can take my time enjoying hot beverage.

Love the mug. Keeps my coffee at temperature I set for as long as I need it to be. Easy to pair with phone. Also easy to clean after use

Worth every penny! Would recommend for all my fellow neurodivergents out there that have taken a sip of coffee only to realise it’s been cold for 20mins whilst you’ve been doomscrolling on the socials. Buying another one for the wife!

The look and feel if the ember mug is extremely premium. My first use really caught me off guard when 30 mins later it was still perfect temperature. Beyond the obvious, the app has many more features like timers for different teas, temps for different beverages, and recipes. Its way more than a mug.

Loving my Ember! I wasn't sure I was going to really use this, since it was a gift, but I love it. I used to chug my coffee because it would get gold to quickly for me, but now with the Ember, I can take my time and really enjoy my coffee. The battery life isn't fantastic, about 50 minutes, but I do keep it on the charging coaster, so there is not need to worry about battery life. Highly recommend the Ember mug.

I love drinking hot coffee, and this mug made it perfect to drink hot coffee and teas. I don't drink coffee too fast, and regular mug cools it down fast before I even get to finish the coffee. However, this cup made a huge difference. It's easy to setup and use!

Great quality, ease of setup and the app works well. Little pricey, just wait for the sale.
