Customer Ratings & Reviews

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

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

This mug does exactly what its designed to do! Can’t recommend it enough!

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.

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

Cool idea. Battery does not last all day. It holds a good amount of coffee and the 10oz cup is too small.

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 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!

Works really well, the price and limited colors are the only thing that keep me from giving it 5 stars.

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.

Works very well but the price is quite high. Keeps liquids at temperatures I like.

This mug does exactly what it’s supposed to do! Just keep in mind that the mug works even better with a lid which will help maintain a uniform temp, otherwise the Mug will cool a little if you’re in a cold environment. I purchased a universal mug from Amazon since it’s virtually impossible to get an ember one. For the price, you would think a lid would be included.

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!

Pros: Does keep your beverage hot for a good hour. Cons: Bluetooth connection drops all the time. Have the biggest mug yet still feels like not enough compared to normal mugs. Need to wash immediate after use and put on charger so it's ready for next use.

I like this cup. It looks nice and funtions perfectly. But the battery just doesnt last long enough and it takes a while to charge. If youre the type if person that drinks coffee all day, maybe get a thermos. If you just have a cup if two for breakfast. It works 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.

I received this as a holiday gift and wasn’t sure how often I would use it. Then I got my seasonal cold and it is a lifesaver! The app is great as I can track and set the exact temp of my tea. The cup knows when it’s empty and shuts off!

I bought this after I noticed a friend had one. I am a tea drinker (especially in the winter). This cup is great for keeping drinks warm. I like that you can adjust the temperature as you like. There are also preset temperature recommendations for specific drinks.

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