    Max temperature is ridiculous

    I thought it was a great idea, but the instructions are not easy to follow. And, even worse, the max. temperature is 145! I want the cup to keep the drink HOT, not just very warm. I regret buying it. And it was a birthday present from my mom. :(

    My wife has had this mug a few days and loves it. I did buy a silicone lid off Amazon that held to extend battery life because it traps the heat in. It has a default heat and you can turn it up in the app. I think they are a little expensive for what they are but I bought it on sale.

    Mug is nice. The connection to the app is horrible. The reviews on the app are all 1 star with reviews. Id check the reviews on the app first before buying this. It worked for a week then stopped connecting. Tried all there solutions and non would stick.

    At best, charge is good for 30 to 40 minutes. If phone leaves it's area, it loses connection and does not reconnect, have to re pair. Can't give no stars.

    Battery no longer holds a charge. I've had it for 2 months. The 3 hour advertised hearing is on the lowest temperature. It can keep coffee hot for no more than 1 hour and 45 minutes. App hardly works. Required constant resyncing

    Absolutely horrendous mobile app. Never seems to connect. Absolutely horrendous hardware, scratches easily. Horrible to hold, poor ergonomics. Does not offer USB C In short, you are much better off saving $100 an instead going with non-brand competitor.

    Not a fan of a $120 mug that only holds the temp for 80 minutes, max. And the Ember customer service is less than helpful. The app continually disconnects even when the phone and mug are within inches of each other, after successful BT connection.

    I purchased this mug a year and a half ago and it stopped working. I contacted ember and they would not provide a replacement mug or even a repair option. They only provided me a discount of $22 dollars to purchase a new one. Mug was great when it was working but longevity, lifespan and along with customer support from ember does not make it worth the purchase
