Almost RETURNED it, made 1 change, and now completely WORTH THE PRICE!

First, the Ember Smart Mug does exactly what it says it will do. So it would not be fair to give it less than 5 stars. If you set the temp on your app to 145, it will keep your drink at 145. It is easy to use. Once you have paired it to your phone initially, you never have to think about it again. Just hand wash it, put it on the charging coaster, and it will ready the next day. BUT DOES IT SOLVE THE COLD COFFEE PROBLEM? Ember is expensive. For that price, it should ensure I never have cold coffee again. Unfortunately, that is not entirely true. Ember will keep your coffee hot, but only until the battery runs out. For the 14 oz mug, this takes around 1.5 hours when fully charged. Like most coffee drinkers, you might down the first cup in 15 minutes, the second over the next 1/2 hour, but that last cup may sit on your desk for an hour or more while you're busy. Then when you get a moment to take a sip; ugh, cold disgusting coffee. So the WHOLE story is that Ember will keep the first and 2nd cups piping hot, provided you finish them within the 1.5 hour battery life. But honestly, I didn't search for a $120+ coffee cup for the first 2 cups of the day. I searched for a way to keep that 3rd cup hot, for an hour or more if possible. My first attempt to work around the short battery life was to use a standard coffee cup for the first 2 cups, and then use Ember for the 3rd. This did help, and the 3rd cup stayed hot longer. But not long enough for me. And should I really have to jump through extra hoops for a coffee cup that costs over $120?? I didn't think so and had made up my mind to return it. DON'T GIVE UP, THERE IS HOPE! Thankfully, before giving up and sending Ember back, I searched on Ember's website for ways to extend the battery life. And there I found the HOLY GRAIL... EMBER can heat your coffee while sitting on the "newly redesigned charging coaster", WITHOUT using your battery! WHY didn't I find this sooner! All I had to do was move the charging coaster to my desk, instead of next to the coffee pot. Clouds parted, stars aligned, and now my 3rd cup will stay hot all day if I want. And I don't notice any difference with the coaster on my desk. It is so slim and sleek, I don't even notice it sitting in that spot that was reserved for my coffee cup anyway. FINALLY, HOT COFFEE ALL DAY! I would give Ember 6 starts if I could, for finally solving the cold coffee dilemma. Thank you Ember for such an amazing product. Might be worth HIGHLIGHTING the ability to keep your cup hot for hours provided the charging coaster is used.

A daily luxury I’m completely hooked on

I use my Ember Smart Mug every single day, all day long, mostly for herbal tea, and it has honestly become one of my favorite little indulgences. Being able to set my drink to the exact temperature I want and have it stay there consistently is a luxury I’ve become completely addicted to. No more lukewarm tea or coffee—every sip stays just right. Because I use it throughout the day, I usually keep it on the charging coaster, which works great for maintaining that ideal temperature for hours. The auto-sleep and motion detection features make it incredibly easy and convenient to use. A small note: you do need to be careful not to get the charging coaster wet, since that can damage the charging pins. I also ended up buying an off-brand charger and lid, and both worked well for me. I loved mine so much that I bought one for my husband and another for my daughter, which really says it all. Overall, this mug is an absolute game-changer and the perfect everyday indulgence for anyone who loves coffee or tea at a truly consistent temperature.

Daily Use for a Year — Still Love It

I’ve been using the Ember Smart Mug 2 almost every day for about a year (I skip caffeine on Saturdays), and it’s easily one of my favorite purchases. I haven’t had a single issue with it during that time. What I like: Keeps my coffee at an exact, consistent temperature once set The app lets you dial in your preferred temperature, and the mug remembers it afterward Build quality feels premium, and the copper finish looks great on my desk Works especially well when paired with a sliding lid to extend battery life With the lid, I rarely need to use the charging coaster while drinking What could be better: The app can be a bit annoying to use, especially during initial setup Battery life is short without a lid, so slow sippers will want the charging plate within reach Once everything is set up, the app becomes mostly hands-off, and the mug just does its job. If you like your coffee or tea at a precise temperature and tend to sip slowly, this mug—especially with a lid—has been a daily essential for me.

Worth the Upgrade!

This has been a game changer for keeping coffee or tea at the exact drinking temperature without constantly reheating it. The app control is easy to use for setting preferences, and the mug maintains a steady temperature so every sip stays just right instead of going cold. The build feels premium and solid, and it has held up well with regular daily use. Battery life is usually enough for a full morning session, especially when kept on the charging coaster. What I also appreciate is how useful the travel version is for being on the go, keeping drinks warm during commutes or longer outings. Overall, it’s a high-quality, thoughtfully designed product that consistently delivers on its promise and makes everyday routines a little better.
