Works excellent and great size for coffee to stay warm

Awesome for someone who likes their coffee hot! Saving a lot of wear and tear on the microwave! If you drink coffee through the morning, it's best to use the recharging stand as a coaster, since the battery lasts about an hour and a half. Highly recommend.

I love the Ember Smart mug. This is my second one, had to buy another one cause my first one stopped holding a charge and I had keep it on the charging base. That one was 5 years old so it was to be expected. I'm a sipper and I'll sip on one cup for at least two hours and to have the temperature constant is awesome!! And I can take it all over the house, it doesn't get any better. That is what Ember does. I highly recommend.

Love the Ember cup. I can have my coffee stay hot for hours! The only downside is the app. It is horrible. Can't pair with cup. Can't personalize. Thank goodness the default temp is 135 degrees, otherwise my coffee would be too cool for my taste. If I could give Ember my review - and I've emailed them multiple times - FIX THE APP!

I gifted this to my mom. The activation and usage is easy once I've set it up for her. All she has to do is press the wanted temp setting on her phone app and it'll start working. Time to heat to desired temperature is about 5-10 minutes. My only dislike is how fast the charge gets depleted and the constant need for charging.

I was worried about the day I would eventually drop the mug and possibly watch it shatter. Well that day finally arrived, yesterday, dropping it directly onto my concrete driveway from about 3'. I saw it hit, expecting it to shatter, but it didn't! Still fully functioning with only a couple small scratches. I thought it was ceramic based but it appears to be metal, maybe aluminum, by looking at the scratches.

Got for my wife she keeps it in her office and loves it. Says her coffee is always the perfect temperature

I tooked off a point because it needs to be recharged after about 1.5 hours

The Ember mugs are excellent. They perfectly solve the problem of trying to catch your hot drink during the short window of perfect drinkability before it gets too cool. Just set your preferred temperature using the app. It might take a while for you to learn through experimentation what your preferred temperature is, but one you know, you know. There are two sizes. My first size was the 10oz. mug. It is slightly too small to hold all of a Nespresso Virtuo coffee, and barely holds 10oz. from a Keurig. I was pleased when they launched this 14oz. size. It suits all my needs so I recommend paying the premium for the larger cup. My first cups where white. They tend to stain after some use. Therefore you might be more satisfied with a black or blue mug. Be careful with the charging base. The two little electrical elements that power the cup are fragile. Place the cup gently on the base. Don’t set it down too aggressively or you can break them. You can buy a new charging base but it isn’t cheap.

I love coffee. I love this mug. Love to drink my coffee from this mug. It keeps your coffee warm. I have had my mug for about 7 months and this is the only cup I use. I use a single serving machine with pods - coffee is not the best but it is convenient. One of the negatives is the coffee doesn't get hot enough so when drinking from a regular mug it cools down quickly. the EMBER mug solves that problem. So, now I can savor my coffee without trying to gulp it down- no need to reheat in the microwave. The only downside is it can take some time to recharge. I forgot to put the cup back on the charger after washing it and was so annoyed at myself when I realized I would have to use a regular cup. Always remember to place the cup on the charger after cleaning so it's always ready. the copper color is really pretty

This thing keeps my coffee at a perfect 140F for me. Only problem is if my phone is away from the mug it shuts off. Now i use this at my office job and sometimes i need to step away from my phone and need my phone. So when i walk away the mug and app disconnect and it shuts off. Its an annoying thing that just happens.

I love this mug. So much so that when I saw it on sale I bought an extra one in the 14oz size for the house. It’s my go to for tea, coffee, and sometimes soup. I recommend finding a temperature you like and setting it there. Once that’s done you pretty much never need to use the app if you don’t want to.

If you ever need to complicate a cup of coffee, get one of these. The cup itself is great. Very sturdy…if not heavy. Keeps coffee warm…when it works. Most reviews on other sites fault this to the app, which is glitchy, at best. When I get annoyed, I revert back to my little coffee hotplate(which only cost $20 and works every time I turn it on), or the microwave…and you can’t use the Ember on/in either.

This is the 2nd Ember I have bought for my wife and she loves it. The first one lasted 4 years with daily use. This one is slightly larger than the old model. The Ceramic outside feels great and the coffee always stays at the desired temp.

It’s a great product so far got it about three weeks ago and it definitely has done its job very well. I do think that it is a little bit pricey but thanks to Best Buy it was a deal of the day . I was very surprised at how great it works and the look is amazing.

The design and how the mug works is well done, being simple and easy to use. As in, you aren't having to go through the annoyance of having to plug this in. You just place it on its mat at any angle and the pins will pick up the charge on the circular tracks wherever they are. The mug has a nice solid, sealed feel to it and the charger is very light weight.

Bought for my mother in law as a gift. She loves her coffee scalding hot so she loves this cup. She could go take a shower and when she comes back to her coffee mug, the coffee is still hot! If you drink lots of coffee be sure to get the 14oz. It doesn’t look big so I can’t imagine how the 10oz compares.

My husband is a slow coffee drinker and was always have to reheat his cup. This ember cup has been a great solution. I recommend purchasing the larger cup if you are using a Keurig type machine.

Bought this for my boyfriend and he loves it! He prefers it over an insulated mug, because it stays hotter and at just the right temp. It is a little pricy, but it's great for someone who works in tech and loves to have cool gadgets.

Decent cup. Works as advertised. Battery depletes fast when in use however.
