    I love this mug! Sitting on the charge base on my desk I can keep my tea warm and drinkable for however long I need, and carrying it around the house on battery for an hour+ is great. It’s magical!

    Mug size is misleading

    This mug definitely does not hold 14 oz. When filled with 12 ounces of water it is almost at the top, no room for cream. This is misleading.

      Hi Paul, thanks for your feedback! While we are confident that the 14oz Ember Mug will fit 14oz of liquid when filled to the brim, as coffee lovers we totally understand wanting a little extra room. For customers that value volume, we recommend our Ember Tumbler, which comfortably fits 16oz of liquid and comes with two different lid options so you don't have to worry about your coffee spilling over. We appreciate your support and hope this information is helpful! Ember

    This is a decent product. The inner ceramic coating is delicate though. Cannot use metal for stirring. App is not great.

      Thank you for this feedback! For best use, we recommend using wooden or silicone utensils for stirring and avoiding the use of metal spoons as this can damage the mug's coating.
      Our support team is also here to help if you have and additional questions! Please feel free to contact us at support@ember.com, so we can help! Ember

    A better option than the 12 oz version and with a thicker wall which hopefully makes it more durable

    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.

    Amazingly hot coffee!

    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.

    Works 90% of the time and works well, but sometimes it likes to think it’s empty and does not heat up. I know a few times it was operator error, but other times it has a mind of its own. Overall it’s used nearly everyday and enjoyed.

    Fragile

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The product is a great idea, reducing the need to constantly head to the microwave to warm your coffee, however, the design for recharging the mug is flawed. Having three dimensional pins on the charging coaster come in contact with a mug that is fairly heavy, is a design flaw. I bought two of these mugs, and ran into the same problem with one of the pins being pushed back into the coaster, which prevents the mug from being charged. Returned the item.
