    For a slow cafe drinker like me this cup is amazing, I follow an IG account and realized she had one of these and got me curious to wanted to try, Keeps my cafe warm without having to reheat and that I like a lot.

    The cup does what it says and will keep your drink at the temp you want for a couple hours while off the charger. One call-out, if you don't get it put on the charger perfectly, it won't stay charged. Not a huge issue but, a watch-out. You will realize it the first time you go to grab it and it is dead but, has been sitting on the charger overnight. I would probably buy again and if the price comes down, I would definitely buy again.

    Bought this for my wife as a birthday gift and she loves it! She tends to abandon her coffee around the house when it gets cold on her, since gifting her this mug, no stranded coffees! She loves that she can adjust the temperature using her phone unlike some other coffee warmers we’ve purchased before. 10/10 would recommend.

    My husband bought this for me for Christmas. I work all day at my laptop, and I'm always complaining that by the time I drink my coffee, tea, or hot chocolate, it is completely cold. This cup works are claimed, and will keep your drink warm until you finish it. My only complaint is that it is small (which is why I took off one star), and it only holds 8 ounces. I think they might make a larger one, and wish I had a larger one.

    Great coffee mug for my WFH mother! No more having to get up and go to the microwave to keep reheating. Keeps it hot and fairly fresh vs that reheated coffee taste

    Perhaps I am not understanding the directions correctly but this is not working reliably. It is sometimes tempermental in the length of time my coffee remains at drinking temperatur especially when after being charged it sits on the holder.for several hours. It shuts off even though the light shows its on. Dont like the idea that it takes 1 1/2 hours to fully charge. Cannot be used for my first cup of coffee in the morning and dont want to leave it overnight charging. Will be calling Customer Support before returning.

    The only heated mug you'll ever need, honestly. This is a fantastic little thing that seems to heat fairly reliably. The only hitch is that software is dependant on the bluetooth ability of your phone, so connecting can be finicky at times. But it does indeed keep your beverage at the temperature it stays at better than any other similar cup of same value or less.

    I've had this mug for a while and use it everyday. I just wished they made it bigger and battery lasted longer. I think i can go without it but feel obligated to use since I spent so much money on it. On the other hand, it's pretty to look at! Bluetooth connectivity when I first got was awful but haven't had any problems recently.

    I absolutely love this bad boy. Keeps stuff nice and hot, even reheats stuff nicely! Battery life is excellent, but the coaster is a life saver. The finish on the inside of the cup scratches pretty easily, but other than that it’s durable and beautiful. Highly recommend taking the plunge

    I bought this mug for my wife, as she frequently throws away coffee once it gets cold. The mug works adequately well, but is too small. Our one cup coffee maker pours a 14 oz cup, and this mug is only 10 oz. They do make larger ones, and we should have gotten one of those. It works well and as advertised, just beware of cup sizes and how much you regularly pour into each cup.

    Bought this a gift for someone and they now use it almost every day. It keeps whatever you are drinking at a very stable temperature. The only issue that this product might have is the battery life, but if you keep it on the charging pad at least some of the time you will not face any issues.

    These are not perfect, they are pricey for a mug, the battery only lasts so long, and milk beverages have a tendency to start forming that milk layer on top but despite these issues this is by far my favorite addition to my life in a while. I find myself having warm beverages more often just to use it because the beverage stays at the right warmth for a long time.
