    Junk piece

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

    Beware of warranty fine print regarding corrosion. Bought mug for less than 2 months and got corrosion on the bottom of cup and on the charger. I cleaned and dry every time before charging. I don't write review but with expensive item last 2 months only. Contact customer support and corrosion is not covered. Within 2 month it's $130 junk. Reply from Ember Support: Thanks for reaching out and providing these photos. Sorry to see this happened. From the images shared, it does look like there is some corrosion damage on the bottom of the mug. While corrosion is not covered under warranty, here at Ember we want to support our customers as best we can and offer an out of warranty replacement for the mug at an additional fee.

    This cup really keeps your drinks warm and thats a big deal. Something i didnt known I needed until i gave it a shot! I do wish the battery lasted more than an hour since i am not always around the charging coaster (which allows unlimited battery when the cup is using it).

    Charge only lasts for about an hour. Other than that, it’s great! I think it’s overpriced. I have seen similar cups in the 40-50 dollar range.

    If mug not on charger, the battery not last long (less than 2 hours). It is kind of difficult to turn the power button on/off located on the bottom of the mug.

    Does a good job keeping the coffee and tea warm for an extended time without having to be in tumblers. The price is on the high side for this basic technology though.
