    This mug has changed the hot coffee game for me! Normally hot coffee is the perfect temperature for such a short period, but now this can keep it just right for hours!

    Absolutely love this Smart Mug. It does take awhile make tea in but if you already have hot liquids in it works great. It’s not dishwasher or microwave safe. It’s notifies your phone once it has reach a specific temperature and indicates battery life. The smart liquid technology is very cool.

    This cup is what I needed at work. I can come back to my desk and my coffee is still the perfect temperature. It heats quickly and shuts off when empty. I am pleased with this purchase.

    It’s amazing that I get to drink it coffee even after I forgot to finish it 45 min later! No kore microwaving it 20x a morning bc I leave it sitting while running around! I also got the lid separately and that is a must I prolongs the battery life so much!!

    Keeps my coffee at the perfect temperature for me. I love being able to change my preferred temperature via the app and it will increase or decrease the temperature in a few short minutes. Ember is the only mug I use to drink my coffee in anymore

    I bought 2 of these over a years time. The first seems to working OK but it is white and terribly stained from coffee. I followed instructions for cleaning but it is still brown on the inside. The second was blue and I thought that would look better being a dark color. Unfortunately the blue one would not maintain temperature when half full so sent it back. I like the idea of keeping beverages hot but it is s high price to buy. Check out its performance while you can take it back.

    Weekend mornings will never be the same. I love this mug so much! It really good for a couple hours of warm cups of coffee. I will fill it and then come back 10 minutes later to a perfect cup of coffee, instead of a cold cup like I used to.

    This mug is amazing. It is the perfect size for a big cup of coffee and keeps it hot for a long time. My husband loves it. The handle is a really good size, too. I would definitely recommend this product; you won’t be disappointed.
