Customers are saying

Customers find value in the temperature control feature as it allows them to set and maintain their preferred drinking temperature, ensuring their beverages stay hot for an extended period. They appreciate its user-friendly design, easy cleaning, and the variety of colors available. However, some customers have concerns about the battery life, size, and price of the mug, as well as the requirement of using an app to adjust the temperature.

    Gone are the days when I go to the microwave every 30 minutes to reheat my coffee. The only negative thing about this mug is that it doesn't hold charge enough. I find myself leaving it on the desk, instead of the coaster, and sooner than later get a notification about the battery running out.

    I like it, but wish I had bought the larger one.. it says 10iz, but 10 takes to rim, so really only holds 8 comfortably.. it does keep coffee warm - so it does its specific job..

    Great mug, keeps your beverage hot. I got the 10oz size, but the 14oz might have been a better choice for me. Only thought would be to have a more ergonomic handle. The thin profile of the handle is a bit tough to hold, and it’s a bit small for even my fingers to fit through.

    I got this mug because my office is chilly and my desk is right next to a cold air vent, which always makes my hot drinks cold really fast. This mug keeps every last drop at the perfect temperature! I knocked off one star because setup was a bit if a hassle, the mug wouldn't stay connected to my phone (bluetooth). I had to reset the mug and reinstall the app several times. But once you set the temperature you want you don't need the app anymore.

    Love the mug, keeps it nice and warm at the temperature I want. Love that it it’s pretty big since I do drink plenty of coffee in the morning. Mug actually has stopped working couple days ago and I’ve had it for 4 months, contacted Ember they will be sending out another mug since it just completely stopped working, doesn’t light up or anything. But other than that works great, keeps it super hot if I put it on highest which I love since I look forward to my coffee and I work from home so I spend all morning drinking it. Love the purchase.

    This item works well, heating the coffee to the perfect temp and keeping it there. The only reason i have it at 4 stars instead of 5 is because the Bluetooth connection. The connection between the cup and the app go out quite frequently. It wont recognize the cup so you have to delete it and re add the cup way too much.

    My wife, son and I each have one of these. They are fantastic! No more getting up in the middle of a cup of coffee just to put it in the microwave just to heat it up. A little pricy but worth every penny. I'm thinking about getting one more for the road. Best Buy had to do a little scrambling since one was out of stock locally. They found one in another store and it arrived one day later than the other two. They also kept me informed of what was happening and when I could expect it. Fantastic product and fantastic customer service!

    I am impressed with the app. Has several presets of heating. You can save your own settings too. Choose color of led for identification. But more importantly, it keeps your drink to the desired temp. Use this with the coaster charger and you have yourself a hot brew throughout the day. I should have purchased this sooner. Heating drains the battery a lot. You need to use the coaster charger to keep it up and running. No biggie. It still is a coaster after all, blends well. Note: you might want to get the bigger cup.

    I bought this as a birthday gift for my husband. He loves it and uses it everyday. It's so convenient sitting on his desk and keeping his coffee at the perfect temperature all the time. And it washes really well too. You don't need to scrub it. Just rinse and it's clean again. And maybe because it's black, I don't see any coffee stain. I may consider buy one for myself.

    I bought this for my husband bc he works from home and always leaving his coffees to sit and get cold. He didn’t ask for it, and kind of gave me a weird look when I gave it to him, but now he’s a total convert. He’s in love. He uses it everyday, all day, and tells everyone about how great it is. The only thing is that he fills it to the brim when he pours out of the keurig. I probably should have gotten the next size up.

    I love this mug so much and the fact that my coffee stays hot all day is amazing. I generally forget my coffee when I’m working so I constantly had to keep going to the microwave and warm it up again. Love this product and also bought one for my sister and she absolutely loves it too.
