Customer Ratings & Reviews

great temperature controlled Mug is 1. easy to use. 2. convenient. 3. heating speed is very fast. 4. power saving. 5. continuous heat preservation effect is very good. 6. It is suitable for self use and gift giving.

This is actually neat. Keeps my coffee at the temperature I prefer and keeps it there. The price is a little high but it is new in the market.

Very happy so far with this mug. Keeps drinks hot at the temperature desired and also has presets. I used the cup for about an hour at 135° F with coffee, which was perfect for me, and had 20% battery left. So in total I would say the battery lasts from about an hour and twenty minutes to an hour and a half in this setting. I also like that the bottom of the cup does not get hot, so I can hold it without burning my hand.

The actual area in which to hold liquid isn't actually that much but it was just enough for me to enjoy my cups of coffee. Sometimes the app to control the cup is kind of funky so I don't use the app that much.

We LOVE these mugs! We now have long-lasting hot coffee, with each mug set to a separate temperature, based on my and my wife’s preferences. The mugs are easy to use, easy to clean, and look great.

I love my Ember mug. Very easy to connect to the phone. Keeps my coffee/hot drink at the temperature I like. At this price, I bought the pack of two, one for myself and one as a gift. It's worth it!

Beverages stay hot for the most part. I have mine set for the maximum temperature of 145 degrees and more times than not it automatically resets itself to 130 degrees but you don’t know that until it’s too late. Cup doesn’t hold enough liquid - needs to be bigger. App doesn’t always connect to mug. Cup says it’s ceramic but it feels like plastic or metal. Maybe wait for the next version of the cup before buying.

In general, the mug works well. But the battery/heater takes up a lot of space at the bottom so it doesn't hold as much as you will think at first. Plus, it will occasionally think the cup is empty when it isn't, so it will shut off and your drink will be cool when you go to take a sip. But the rest of the time, it's pretty amazing to take a sip 15 minutes after pouring and it's still at a perfect temperature.

If this bundle wasn't on sale, I wouldn't be nearly as happy with this purchase. The battery doesn't last very long (around 45 minutes) and it won't heat & charge at the same time if the battery runs out. If I set it down on my desk instead of the charging coaster, the battery runs out pretty fast and then my coffee is cold and the mug won't reheat it while it's charging, which kind of defeats the purpose of using it in the first place.

Solved the problem of having to run downstairs to heat my coffee every 15 min! Love it. Just wich it had higher capacity...

I thought this was going to be something better. I drink my coffee slowly. This mug battery only last about a half hour or so. It will keep your coffee the same temp, but it requires very frequent charging. You'd be better off buying a knock off Yeti thermal cup for $8 to keep your coffee hot. It does have a cool app, and neat lights, but for me.... Meh.

Works well to keep coffee at desired temperature only issue is battery charge doesn’t last a long time

Another silly product that you don't need but is great to have. I really enjoy my coffee but it always gets cold. This solves that problem. I wish it would stay charged longer than 1 hour.

I have been using this mug for a few weeks now and I really do enjoy walking away and coming back to my cup of coffee still hot!! I recommend this mug as it is so easy to use and keeps my coffee hot.

I really enjoy my coffee staying hot. Wish battery lasted longer and price was a little lower.

Connectivity is lacking and app is not so great. Cups work great when they are working though

For hot-drink and technology enthusiasts, this is the perfect splurge gift. I have an Ember mug myself for nearly a year, and I got this set as a gift for two different family members. It was greatly convenient that it came at a discounted price for the bundle. A couple of things to know: - it's not a thermos, it's not about the duration of the temperature but the accuracy - the white mug is prone to staining and visible marks from metal spoons - the mugs in this pack are the smaller version, and so they will not hold as much but it isn't a problem if you don't need a lot. Highly recommend !

My wife and I have been wanting to purchase Ember mugs for the longest time. One day, without even looking into purchasing these, Best Buy had them on sale. We took the plunge and couldn't be happier. As a matter of fact, we love these mugs! We don't see ourselves using a regular mug for our coffee and tea anymore. Ember mugs keeps our beverage hot until the last drop.

I bought this for my wife. She loves tea and drinks it slowly. So much so that she was constantly having to re-heat it in the microwave. This cup is as advertised. It is easy to connect to your phone through an intuitive mobile app. The app allows you to set your target temperature, and the cup keeps your beverage at the selected target temperature once it is reached. It will last all day on the included coaster, and I believe the battery lasts about an hour off the coaster. I got it on a deal of the day for $50, and I picked up an extra coaster for $10.

Nice mug and like the ability to control temperature. Battery life is bad so really only is good when sitting at desk with charging plate. No sure if it is worth the cost when a hot plate can do the same (minus temperature control). Will be better when they can get battery life to last longer then about 30 minutes.
