Customer Ratings & Reviews

I never knew I liked my coffee consistently hot until I had this mug. Now when I’m not using it, I noticed the temperature declining without it. I absolutely love it! Super convenient. Have bought a second one for my office. 

I had this product for about a week and it works great, but make sure to tell your wife not to put in microwave. It will melt quickly.

The electric coffee cup , it works good but only complaint is the battery life isn’t that long

My wife loves it! She drinks her coffee slowly and it stays warm!

Works great and my gf loves it. She doesnt have to keep heating up her tea anymore lol.

My wife loved her Christmas gift! This has been in use non-stop for the last month. No more cold cups of coffee or tea for her!

Love the copper finish! It cleans well and seems to hold temperature really well.

Purchased for my wife as a Christmas present; she loves it. She can set the temp just the way she likes it via her phone app.

Love this mug. For those that like a hot cup of coffee or tea with out constantly heatingbin the microwave this cup is gor. I truly do not know how i have lived with out it. Best buy customer service is 100% awesome Get it you will love it.

love this cup, keeps coffee hot. I love the new size too.

Bought this for my dad for Christmas and he uses it for work and loves it. His coworkers are wanting to take it from him.

This is great. I used to drink my coffee fast. Or I’d get distracted and have cold coffee, Now I’m not in a rush to drink it, and if I get distracted for a bit, it’s still warm for me!

The mug does an excellent job at keeping the coffee warm. The app is a bit finicky and needs to be updated.

These things are great. My wife and I each have one already. So this was a gift for my father in law. You can take your time and enjoy your coffee instead of trying to scarf it down before it gets cold. Can even enjoy it out on the deck when it’s a little chilly outside because it stays hot. I keep mine at 128

Great mug! Keeps the coffee warm. The size was great.

This cup is both intuitive to use and set up, and does what it says! As a busy household, many a cup of hot stuff (tea/coffee, chocolate) has been thrown out for going cold. This keeps it toasty and drinkable for hours without it going stale. Would recommend.

This mug is AWESOME! My wife never finishes her coffee on the first go around. She always has to heat it up in the microwave later on. I purchased this mug for her and now she never uses anything else. This keeps ANY beverage hot and always ready to drink

This is perfect for working in a cold area (basement). This works as described. The app is easy to use.

I've always enjoyed coffee, but I don't like it too hot, and I don't like it too cold. First world problems, I know. However, my Ember cup has changed my world. I make a cup, wait until it reaches my set temperature (128), and then start sipping it. Amazingly, my coffee remains at 128 degrees from that first sip until the last one. If Maxwell House had not already used the phrase, "good to the last drop", then I would apply it to Ember, which would be more true. This thing is worth it!

Great experience so far. Beautiful color and design and heating system is great.
