    I have to drink my coffee hot, or not at all. This cup is amazing! Coffee maker dispenses at 173 degrees and hottest cup will “hold” is 145 which is nearly perfect temp (the Ember app actually shows you this). 145 temp will give you about 60 minutes of battery life. One thing to keep in mind, this is the 14 ounce version…if you add cream or milk, you can only put 10 ounces of coffee into it to leave room while not spilling.

    It was fully charged, synced to the app, and it was working fine during the warming phase. Within seconds, the cup disconnected from the app and stated that it needed to be synced. We started over: the cup was charged and synced. Again, during the warming phase, it disconnected and instructed us to sync the cup to the app. We are returning it.

    This has been our biggest gift hit this year. People love it and use and rave about it so much that I’m putting the word out I want one for Father’s Day. Seems a little selfish to fork over the $100 bucks just for yourself but if I don’t get one as a gift I just might.

    This is my second mug. I have one for the office and one for home. Works well and the battery life is good for what I need. I also bought it when it was on sale so that was a perk.

    Cool concept and can work for some. The app seems to not be the best and taking care of the mug is a chore itself. Returned it after just opening and testing it.

    The Ember mug is a high quality item. The description is very accurate. Performs as stated. This is perfect for those who enjoy a hot beverage - without repeated trips to the microwave. Highly recommended.

    Review my 2 years Ember cup

    This is very useful, I love it, been using this every other day since October 2020. No scratch, no damage, and no issue. Just be a gentle wash right, I use a baby Bottle Brush stand-up from Target store, not with a metal wire head, better use only plastic to avoid scratching the cup. Never put them in the sink dirty dishes, put cups aside on the counter. My ember cup still looks like a new BMW.
