Temperature Control Smart Mug, 12 oz, Black, 2-hr Battery Life - App Controlled Heated Coffee Travel Mug

Of course this Ember mug is punitively expensive, but as luxury, technological products go, this is the business! It arrives beautifully packaged - as if an Apple product. The mug connects wirelessly to a sleek ‘saucer’ which connects to the power. The internal battery keeps all manner of hot drinks piping hot - at a temperature of your choosing - for at least two hours. The scrolling display is beautifully integrated in the sleek exterior. I love its look and feel and only quibble about the modest 350ml capacity. Hand-washing only, obviously but this product is a triumph of technology over a very mundane issue: cold coffee!

Mug worked fine on the charger but the battery would not charge and it was blank when lifted it off - I had chucked out the box. I have started an amazon return and boxed it up and will get back to you all to see if the defective good was properly refunded. They had no black mugs left so have ordered from another website as I really wanted one and the idea is sound if the mug works.

Really good cup to keep hot drinks hot for almost half of the day

I bought this on the recommendation of a friend who knows I like my coffee! The concept is a great idea albeit an expensive one. I should have known that all wasn't well when I could not get the mug to charge, but 2 factory resets later all was well until yesterday morning when it stopped working altogether. I tried another hard reset and then another - no joy. Checked the charger, changed the plug nothing. Ember offered to replace if I sent numerous videos but told me I would have to wait another month, understandable until I looked on the Amazon site and saw that I could have one supplied by Ember the next day. This left a bitter taste in my mouth! The idea is good but the design could have been better. I particularly disliked the mouth piece which you have to push down to use which means that you can get burned if you are not careful. Not sure that I shall be spending my refund money on a replacement

The good: sleek beautiful design, super simple control & operation. Keep s temperature well for about 90 minutes. The bad: about 100 ml too little volume for me but might be sufficient if you choose small or medium size coffee normally. Obviously would like a little longer retention but understand that impossible with size issues. Beautiful well designed product, will buy again & again & again.......

Battery’s life is about 1 hour especially if it’s heating up away from the base! But hey I have a black one and my wife a white one and is the first Thing we turn to in the morning since, I bought them!

Great product, but the lid broke after 5 months and the distributor has gone bust. Owner left the country. Not happy and amazon not interested in a refund. Buyer beware

Very stylish product. Charges quickly and keeps my coffee at desired temp for couple of hours. Only negative is it does not hold as much liquid as you would think.
