Customer Ratings & Reviews

Works as intended! I have to get used to how hot I want my coffee...Only complaint? Battery life is kinda low. Best to plug in near your workstation.

I got the v1 of this mug for my mom for Mother's Day, and she seemed to enjoy it so much that she got me the v2 for Christmas. This mug is amazing. There are a lot of complaints on the app that they've had trouble maintaining connection with the mug in order to control it, but thus far I've had no problems whatsoever. The commenters may be talking about the previous version of the mug. I used to love to drink tea, but I usually had it on my desk while playing games on my PC and sometimes I would get so focused on what I'm playing I would completely forget about my tea until fifteen minutes later. By then it was cooled down and unpleasant, and I was sick of having to microwave my tea over and over. This mug has proven to be a HUGE convenience. I'm drinking two cups of tea a day again and I'm so happy to be back in the habit. I can sit at my computer for hours and drink the same cup of tea without getting up every 20 minutes to microwave it. It stays at the perfect temperature I enjoy my drinks at (anywhere between 130 and 135 degrees, if anyone who's looking to buy wants a ballpark of a good temp), and the app has a built in timer for steeping. One of the best things about the app is that it tracks the temperature of your drink and tells you when it's reached your desired setting, so I never have to burn my tongue again trying to gauge if it's ready to drink. I'd recommend this to anyone who drinks a hot beverage on the regular at home. The only downside is that I have so many cute mugs at my house, and I never use them anymore because this mug is so top notch.

Would not sync with cell phone in the app, also did not keep beverage hot

This mug makes cold coffee a thing of the past. I personally drink black coffee and always struggled with either burning my mouth or drinking lukewarm/cold coffee. The Ember keeps the coffee at the perfect temperature for me. Two gripes with this product though. First, if you're keeping the coffee warm, the battery is gonna go kind of fast. You'll definitely need to charge it while drinking your coffee if you're someone who has a cup of brew with you all day. Second, is the app, it's a bit of a nightmare to use. The mug will disconnect from a very short range and doesn't use the standard Bluetooth connection function on your phone. It NEEDS the app to connect to anything, which is bad if you separate your phone and coffee for any amount of time, as you'll have to hold down the power button on the bottom of the mug and repair it to your ember app. I'm overall very happy with the mug though, the material is nice, it helps cool the coffee faster, and keeps it warm and enjoyable to drink.

Lukewarm coffee? What’s that? You never knew you needed this but once you have it, your coffee experience will never be the same. I use mine everyday. Tip: set your temp and forget it. Only like the app for notification and updates / get an extra charging coaster if you can / get the 14oz / Pro tip: if you have a travel mug lid that fits, use it on this cup esp if you are outside or away from the coaster. It will keep you coffee bug free (gnats aren’t my kind of protein -lol) and help maintain the temp potentially extending the time between charges

Pretty good. It definitely keeps the liquid warm when on the cradle but after about an hour my coffee tastes burnt. I am in and out of my office all morning so I do leave my coffee there for several minutes at a time. However, it does the job.

I got this for my Mom for Christmas and she loved it. She’s always leaving her coffee sitting around the house and it gets cold so then she has to warm it up in the microwave. She loved that fact that she doesn’t have to worry about her coffee getting cold anymore!

This cup is worth the purchase to keep your drink warm or cold in the perfect temperature you want. User Friendly and durable

Absolutely love this mug!! It keeps my coffee and tea warm for a long time! I did have some issues initially getting it to connect to my phone, but, once it did, it's been great ever since! I do wish it was just a little bigger, otherwise, it's definitely great! Need another charger stand so I can take it to different levels in my house without worrying about losing charge.

Amazing. My wife nurses her coffee in the morning and usually ends up reheating it a couple time. This mug does exactly what it says it does, keep the coffee at your desired temperature for over an hour. It loses a star because for the price I wish they lasted longer than 2 years but she likes it so much I had to repurchase.

Every time I take a sip of my coffee it’s absolutely the perfect temperature. Best cup of coffee down to the last drop. Now I don’t have to reheat my coffee a million times. Thank you Ember!!!!

When it goes on sale or super sale you have to buy never had a complaint give as gifts to others after getting my own. Keep it out of the dishwasher and will last a long time is my experience.

We've been using two of these in black and white daily for 4 months and love them. We wash ours by hand and have not had the issues the other reviewers have experienced. We keep the setting at 150 degrees and our coffee is hot with every sip. Going to purchase two more for gifts.

Excellent product and easy to charge and also easy to clean

Poured 2 cups of coffee at the same time, one in a regular mug and the other in the ember. The regular mug had only kept the beverage warm for about 15 minutes while the coffee in the ember stayed at me desired temperature. Highly recommend for those who like to sip on their coffee and not down it in 10 minutes.

This mug is simply the best- it hears up as soon as yoy put loquid in it and it keeps it at the preset temperature- simple as that.

I bought this for my wife for Xmas. I’m always on cup two before she finishes her first. This is amazing. She sets the temp from her phone and every sip of her coffee is the same temp. Great purchase.

I am not the best person to write a review since I’m not an avid coffee/hot tea drinker. Even with that said I think the mug is great. It even makes for a good cup of oatmeal (I tried it this morning) The only downside is that I didn’t get the larger one.

Purchased this mug as a gift and its very much appreciated. The mug keeps your drink exactly at your desired temperature.

Bought this as a gift for my wife and she loves it! She likes to drink her coffee or tea slowly and before she would always end up drinking them cold. This mug has been life-changing for her.
