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.

This is a really good product. Keeps my coffee hot when I get distracted by work. Normally I would be irritated when I would get back to drinking and it was ice cold. Not anymore!!

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.

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.

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.

Really nice and sleek cup! Keeps liquid hot! Very good!

I like the concept of this mug. Overall it has worked well, 9/10 times getting it right that there is a beverage in my cup. My I main complaint is thst i feel tied to the charger. 80 minutes goes by faster than you’s think.

I’ve been using the Ember Smart Mug every day since I bought it, and I can honestly say it’s a game-changer. I used to constantly reheat my coffee, but now it stays at the perfect temperature from the first sip to the last. The app is super easy to use, and I love being able to set my preferred temp (135°F is my sweet spot).

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.

Mug shows charged to %100. As soon as I take it off of the charging coaster the percentage drops below %90. It doesn’t last anywhere near the advertised 80 minutes at a setting of 136 degrees. When on the coaster the battery still dies if keeping coffee hot and will randomly shut off saying the cup is empty. Notifications show up continuously once the beverage has reached your set temperature. I had to shut them off. I have attempted to contact Ember 3 different times for support with absolutely no success. They never follow up or contact me at all. If it stopped working tomorrow, I would not spend the money again. For the price, I had hoped for a higher level of service from Ember. Realistically, I might have been better off with one of the cheap ones from Amazon.

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.

Works well to keep coffee the exact temperature I like. Easily controlled with app. If not on the charger the battery is enough to keep coffee warm about 75-90 minutes based on my experience. Easy to charge just put it on the charger stand. Easy to clean with soap and water.

Love the mug, definitely keeps coffee hot. Not sure if my coffee maker is off or if this mug doesn’t actually hold 14oz. If I brew a 12oz cup it’s at the brim. Had it for a month and a half now with zero issues

Expensive, let me say that first. If BB did not have it on sale I would have passed on it but it does keep my coffee hot! The mobile app is a great plus as well to control the temp settings. Easy to charge, easy to rinse, and clean for the next use! Not throwing it in the dishwasher for sure!

We love these mugs. My wife has one and I’ve purchased one for several friends for birthdays, etc. We haven’t gotten to test this individual mug out yet, because it’s a gift for someone in October. But if it’s anything like the other ones, we will love it.

Bought this for my wife as a Christmas gift as she always complains about her coffee getting too cold and loves it hot. Bought this on a whim and it does not disappoint. She has made comments it's one of the best surprise gifts I ever gave her and that she loves it. After ~1 year the charger stopped working due to the pins getting stuck and their customer service sent a new one right away at no cost.

I never thought I needed this kind of mug. But it is amazing! Side tracked and forgot about your coffee? No problem. This mug keeps it warm and fresh, as though you just poured it. Easy to clean and love the color.

Like the title states, it is expensive for what it does, but it does what it is supposed to do well. App is easy to to use and the mug holds a charge well. Only cons is price, and isnt dishwasher safe.

I purchased this as a Deal of the Day at a reasonable price. It does take time to get use to it. I'm satisfied with this Ember Smart Mug. I just needed something to keep my Lattes warmer a little longer. I like the 14oz size so there's room to stir without splashing it all over.

Love this mug, especially running around with the kids, massively reduces the chance of me getting back to a cold brew. Love this mug!
