Customer Ratings & Reviews

This mug is wonderful! It is the best mug for anyone who enjoys hot drinks.

Works as is. Easy to use app. A bit pricey though for 10ml mug.

Bought this a gift for someone and they now use it almost every day. It keeps whatever you are drinking at a very stable temperature. The only issue that this product might have is the battery life, but if you keep it on the charging pad at least some of the time you will not face any issues.

I got this cup for my wife for almost free. It popped up on the member sales of the month, and with the money I got back from using my Best Buy credit card from prior purchases only paid $10.

Purchased this as a Mother's Day gift for my mom and she is over the moon with it! Loves how easy it is to use and enjoys not having to reheat her tea and coffee.

Great mug. Very sleek design and keeps coffee warm.

I got this mug as a gift for my dad and he absolutely loves it. It does a great job at keeping his coffee warm. The only thing I would change is that I wish it could come with a lid to make it easier to carry when full of hot liquid.

Have had this mug for a while now and it really is great. I wouldn't recommend it if you use a lot of cream and sugar if you're the type of person that lets your coffee sit around - as with other warmers it causes that "skin" to form at the top... but with black coffee or tea with no cream it is great.

I love this. I'm a slow coffee drinker and frequently my coffee would get cold by the time I finish my cup. This solves the problem for me and is near perfect. The only issue is that it takes a long time to recharge. Oh, and the cost is ridiculous. However, I'm a sucker for items that solve life's little annoyances.

Bought it for my dad who lives up north. He loves it and uses it every day for cold Dakota mornings. He says it keeps his coffee warm for as long as he needs it.

This stylish mug keeps coffee at the perfect temperature! Only downfall- we need a second base so the mug can go to the office and stay charged so we don’t need to haul the base from home to use it!

This mug has helped to not only make my morning better but by making my cappuccino hour better. Ember keeps my coffee to my preferred temperature and keeps there till the very last drop. No more cold coffee after 10-15 minutes; and the coffee does not get the burnt taste that it gets when leaving it in the coffee pot. This mug was definitely worth the investment

This was gift for my wife. She loves it. It gets used every day in her office. It keeps her coffee piping hot, sitting on the charging plate. When used on the couch, reading a book... It lasts just long enough to enjoy a cup or two. I think she programmed it once, and it's worked fine ever since. But, it's expensive. I don't understand why so much.

It is a bit small, I ended up getting the 12 OZ version that I like better, and it keeps the drink warm, not hot but it works. I would like to have an option on the cup to change the temp as sometimes it is a pain to find my phone just to get it set up. But I do like it.

This was a gift for daughter. She said it works great. Keeps her drinks hot at home.

Love it and use it daily. Perfect solution for keeping coffee hot at the desk. I get so busy and sidetracked at times, its great that it keep it my favorite temp during my busy moments.

My Wife simply LOVES this Tea/Coffee cup. the technology behind this is simply amazing. No more aluminum foil to place on top of her cup to keep the heat in. she simply sets the tempter using her bluetooth phone and it remains that temp till the drink is done. A little expensive but worth it.. PS I purchased another one for my sisters birthday present.

After buying countless cup warmers from various companies, which never really worked, i was happy to see something like this. Works as intended. My coffee never gets cold. Definitely worth the money

My husband drinks coffee everyday and has a ton of mugs. I took a chance, and it was a hit. He loves the mug and doesn’t waste coffee because it’s stays hot longer. He loves the app, he’s such a techy.

[Employee of bestbuy] Perfect gift for someone who loves hot drinks but takes too long to finish them. It keeps the drink warm to a preferred temperature and you can personalize the light to your favorite color
