    Gift for my mother a couple years ago, she loves it. She used to complain about waking up and having her coffee, and never finishing it because it got cold while she got ready. This literally takes care of that issue. She isn’t the most tech savvy, but she uses the app just fine.

    I bought 2 of these mugs, 1 for my wife and one for my mother (I don't drink coffee. Both have indicated that they love them. They do require you to get the phone app both that was easy. I battery life is only rated at 1.5 hours but I understand that Ember has come out with a new model with a longer batter life. (I use it to keep my hot chocolate warm as I drink it!!)

    Count me responsible for 8 happy sippers. Bought this for my daughter and her WFH office. She had 2 friends that wanted to details. All were happy, so I gave 4 of my employees this for the holidays. My daughter then got me one for my home office. There as infectious as Omicron, but everyone likes it. Way more useful than you might initially think. WFH, travel, camping.

    This mug is perfect for people who like to take their time and enjoy their coffee, but hate Luke warm/cold coffee. This is especially nice to have for long periods of studying. I would recommend the larger size though, and think it would be well worth the price ( 10 oz just isn't enough in one sitting). Also, the off base battery life is shorter than expected, but sufficient. The app is super easy.

    I love this cup so much I bought one for my mom and my aunt. It makes drinking coffee and tea so much more enjoyable. No more burning my tongue when the coffee is too hot and never having cold coffee waiting for it to cool and then forgetting about it. It’s the perfect temperature ever since time.

    This was purchased as a gift for my son’s Dad, who is not easy to buy gifts. This mug completely won him over. He loves it! Sends our son pics of the app telling him his coffee has reached the desired temperature. There will be no end to his diva mentality now…no other mug will suffice. It’s easy to work with as long as you can follow directions! Hand wash only.

    I purchase this for my wife she really likes it. She uses it all day at work. If you like your coffee at a certain temperature the entire time you’re drinking coffee and then this is a must at first I was thinking this is too expensive for what it only does but after you start using it, you realize it it’s worth it

    I didn’t even know this was a thing until I found it wandering around the store, man do I love this product. There are days where I just chill on the couch and forget I have my coffee next to me and it gets cold, now I don’t ever have to worry about it going cold

    Keeping it HOT

    I got one of these for my Birthday and had to get a matching one for my wife for Mother’s Day. It is an excellent product that keeps “our” coffees hot for at least an hour. It is a little pricey but we thoroughly enjoy using them every morning. The phone app lets you customize your preferred temperature which is so simple. It automatically turns on as soon as liquid hits the cup.

    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!
