Customers are saying

Customers highly value the product's exceptional temperature control, which is frequently highlighted as its most impressive feature. Users also appreciate the sleek design, convenient size, and overall ease of use that the cup provides. While the performance is well-regarded, some customers have noted concerns regarding the battery life and the premium price point.

    Avoid this brick.. Great idea but flawed software!

    My wife bought this for me as a Birthday present. Every time I open the app I have to disconnect and reconnect the mug. I cannot set the temperature of the mug. There is a Firmware update available and it fails to install every time I try and run it, Ember support sent me a list of troubleshooting steps which I have followed multiple times from multiple phones, and nothing works as advertised. I missed the 2 week return window and am stuck with this $130 brick.

    My mother loves this. She never has to re-heat her coffee because she is putting too much creamer in it.

    Coffee stays hot all morning (no more microwaves). But the creamer will get a little odd after a bit.

      Hi Purchased, thanks for taking the time to leave a review and sharing this feedback. While it will be filled to the brim, we are confident the entire capacity of the 14oz Ember Mug is 14oz. With that said, we can certainly pass this feedback along as we continue to improve! We're always looking to grow and improve so if you have any other concerns, please reach out to us at support@ember.com so we can learn more! Ember
