Customer Ratings & Reviews

I bought this Blue model on sale to try before getting another as a secret Xmas present for my Daughter. It works as advertised and I am extremely happy and my Daughter says "best present ever" as she works 2nd job from home at desk for hours at a time. The initial 135 degree setting I thought was a little too hot for my taste but I have gone back to it after trying 125 degree recommended by some Coffee guides. Initial setup for the App was okay but not intuitive that you must actually follow a few extra steps even though the prompts are already saying press "here". It is best to manually sync the cup in your phone's Bluetooth first before trying to follow the App. After that go slow and let the App sync until it gives you the menu. I only used the App to change the temperature and it is not required to keep that setting. If you are going to move the cup from your Coffee Bar/Kitchen often it is best to have a 2nd charger base just to not have to walk back for a charge if you are holding a cup for long sessions in another primary room. Following guidance to not use metal spoons and non-abrasive cleaning and no issues yet with the interior coating after 4 weeks of use.

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.

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!

Love these mugs. I am spoiled by them now, it's so great having my tea at the perfect temperature all the time. Unfortunately, they are finicky and the charging coaster stops working after a while. Still worth it to me.

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.

Works as advertised! Two recommendations: 1 needs longer lasting battery 2 or provide extra charging plate so you can charge in multiple locations.

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 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 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.

Haven't used it much yet, but its been great for teas. I tend to take my time drinking my tea and it's usually cold by the end. This fixed that issue.

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

One word. Perfect. No more cold coffee. Take your time and enjoy without fear that your coffee gets cold.

The Ember Mug is a great gift for anyone anyone who enjoys their drinks to be hot, and to stay that way. They provide you with a nicely-sized cup which not only comes with an app to customize & set your own temperature, but it also has built in thermal technology to keep your hands safe & store all of the heat inside.

app is really well done, mug warms up super fast. only con is sometimes is has connectivity issues

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.

Solid cup. Keeps drinks warm. Unfortunately it's not dishwasher safe.

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.

Got this for my wife as a mother's day gift. She has a habit of leaving lukewarm tea all over the house. She loves it and it prevents her from nuking her tea in the microwave every 30 minutes.

Excellent - works as expected. Keeps coffee the desired temperature for as long as I need

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.
