Ember Temperature Control Smart Mug 2, 14 Oz, App-Controlled Heated Coffee Mug with 80 Min Battery Life and Improved Design, Black

Good:- Does what it says on the tin: Keeps my tea nice and hot for around 80 minutes normally, or indefinitely on the coaster.- It's easy to clean, and the material feels good to drink from. It's plastic but it's a high-quality good feeling plastic.Bad:- The app is dreadful - but you should only need to use it once to set your temp and then you're fine.- If you like your tea VERY hot, it may not be enough. I've set my temp to 61c and it only goes up to 64c, so it's a little close for comfort (I think a fresh cup start around 85c for reference)- It's annoying to remember to charge it back up again after any use away from your coaster.

Wanted a cup warmer for a while but they’re so big these days and have mixed thoughts fed back on them. So I plumbed for an ember mug.. whoop! It’s better than I had hoped. Yes it won’t last forever but do you really want a scummy cup of coffee or tea after an hour or more stewing? (Also best with dairy free beverages or soups!)In my non heated office now the temperature is dropping it’s the best thing ever. When caught on the phone for a length of time I know my drink or soup is going to be just the way I like it. It’s deceptively cool to the touch, easy to clean and gives you a surprise when near the last few gulps when it’s still piping hot at the end. Will be getting another for home when finances allow. Not the cheapest. But the best. And it’s not hard to keep the bottom dry; for all you qi lovers.

I didn't want to hurry to write this review so now that 6 months have passed, this is what I've learned from every day use:This mug stains. It's black so you wouldn't think it would get stained so easily but it's nice sleek finish was toast by a month or 6 weeks in. I realise this is from tea sitting in it too long - but isn't that it's design? It gets rinsed a few times a day and then cleaned well at the end of the day but it's clearly not enough maintenance. I've tried to scrub it out as much as I feel is possible without scratching it and using numerous other things to clean it (soaps, denture cleanser tabs, vinegar & baking soda, etc) Nothing really works which is sad because it looks great out of the box.The app is pretty useless. Good thing you don't need the app to use the mug because it needs constant pairing and makes you want to throw the whole thing out the window. If the app is something you plan to rely on, skip this. It's pointless.The mat has started to become sketchy about charging and I worry that I'm going to have to return this before the year warranty period. I've got it marked down in case it needs to go back because you have to sit it "just right" sometimes to get it to make perfect contact.But why 4 stars? This sounds like a 1 star review, mate! Because the mug really does work. It'll sit there and keep your coffee or tea toasty warm for a good long time. If it's sitting there on it's mat it'll keep it warm until your cat knocks it over or the milk skims over. If the extras and bells and whistles are important then upgrade to something more than the 2.0 or skip this but for me, it's saved money and improved life (less tossed out coffee, less tea down the drain, fewer tea bags, much less milk, etc)

EDIT:I still love this cup. But, in the year I had it, the coaster was replaced twice because the pins kept getting stuck and didn’t connect to the base of the cup to charge. I was careful not to make the coaster wet and this still happened.After the third time the coaster pins got stuck the whole thing went into the bin. I didn’t want to keep replacing this coaster every few months.I always have a tea on the go and this is awesome. It connects without a problem to the app on my iPhone. I have the temperature set to 55c and my tea is mostly always good.I say “mostly” because if I leave it too long, a skin forms on the top of the tea. This normally takes an hour or so to happen, so is probably not an issue for normal use. I get lost in my work and can forget about my hot cup of tea.I also like to drink herbal teas. I use a tea infuser with ginger and lemon. I’m able to pop the infuser in my cup and leet it steep for 15-20 mins before drinking and it’s a perfect temperature.I can’t speak highly enough about this mug, I absolutely love it.There is one negative and that is the tea stains, but I suppose that’s probably due to not washing my cup between cups of tea through the day. So, I suppose this is the o be expected?The stains do come out with a bit of elbow grease and some dish soap, so not a deal breaker by any means.

In addition to Ember's lack of any kind of customer service whatsoever (see original review below..) its also a TERRIBLE product.Its a bluetooth connected mug.. which CANNOT stay connected to bluetooth.I've had it nearly 2 years with 3 different phones during that time.. and its been utter garbage on all three. DO NOT BUY THIS unless you have an iphone.. on Android.. its useless. (as you'll see if you have a quick search for ember android issues)Bought on Amazon, however sold by Ember, Inc.The mug arrived with a minor defect, which is purely cosmetic, however at the price of this it should be perfect.As it was sold by Ember Inc Amazon can't replace and can only offer a refund. As it's currently out of stock and even more outrageously priced than when I bought it, I asked ember to assist.They claim to have no access to the order due to it being on Amazon, despite Ember, Inc being the seller. (So they definitly do have access).

I absolutely love this mug! I also bought the new Sliding lid from their website .It will improve the battery life and you can bring your coffee from home.

It works perfectly and seems long lasting. Great product.
