I got one of these from Costco. My complaint is that it works too well. What I mean by that is it constantly cooks while in the mug. It works wonderfully on black coffee and tea. But I like creamer in my coffee. Since I put creamer in, it essentially cooks to the side of the cup.

I don't like the cup simply for this reason. If I drank black coffee, I would be in love with it.
I guess that's the crux of the matter.

Not as slick looking, but for a whopping 22 bucks you could also get a temperature controlled heating pad to use with your plain old dishwasher safe ceramic mug: https://www.amazon.com/dp/B0779QR...ZB3E1MV1X9
I think people misunderstand what this does. They don't realize you can actually set the desired temperature.

I admit these seem very expensive, and they are. I hemmed and hawed for a while because getting one. I've used it literally every day for the last two years. Absolutely worth every penny.

It'll change your life, well, maybe that's extreme, but mine was worth every single penny I paid for it.
Never seen this before, $100 for a coffee mug is sole crushing to me... but I'm pretty sure I'll be a convert if I get one because I hit the microwave to reheat often. Plus it would be nice to just warm up hands on cold days.

Also, this cup warming/charging system would be a great feature for newer cars similar to built-in magnetic induction phone chargers.

Ah, the time to be alive. Temperature controlled mugs.
It goes nicely with my refrigerator with TV built into the door and wifi washer and dryer.

There is good technology like adding backup cameras to cars and trucks and there is technology making things needlessly overcomplicated. Why a refrigerator needs a tv screen and a washing machine needs wifi I have no idea. This is leading us to look like people in Wall-E

I just don't see who drinks coffee slow enough to need this? And even if you did, 80 minute battery life? I just don't see the quality in this product

The Zojirushi loses about 10F/hour @ 200F. In the target 130F range, it will probably loser closer to 5F/hour. This will cool more quickly from too hot and maintain the exact temperature as long as it has power. If you are very particular about temperature and are willing to spend 4-5X, this is a clearly superior solution. If you have a comfortable temperature range that is met by the thermos, it may end up being a low-value gadget.
Why can't their powers combine?
Then I can have my perfect temperature for 5 days.
I do agree the perfect temp beverage is nice. insulated can only slow down the rate of heat loss (or gain, depending on your use case).

Not everyone pounds coffee. But. Anyone who sips coffee that slowly is also letting it oxidize and changing the flavor. No happy medium. Can't justify 100 bucks.

This is one of the dumbest goddamned things I can imagine. You know what else keeps hot drinks hot? A THERMOS. Enjoy hand-washing your stupid smart mug forever because running it through the dishwasher will probably cause the battery to self-immolate. People buy the dumbest shit.
You know what else isn't dishwasher safe? A Zojirushi vacuum bottle.

Yes, gray vs. blue and OOS online. My local Costco had 30+ on the shelf.

This seems super cool, but my insulated mug is doing the trick.

Legit question for those with this: why not just use a zoujirushi thermos? They can keep things hot for days, are 1/5 the price, have a lid that prevents spillage, and don't require power?

If it's too hot in the thermos, you can always invest in those thermal stones that cool down hot coffee some?

Legit question because I just bought the Costco version…damn Slickdeals.
With you 100%.

I suppose this is good for someone who works from home and sips at their coffee from a mug for hours?

Honestly, a 14oz mug you're gonna fill to about 12-13oz... I'm going to be done with that in 30 minutes.

Anything more goes in a thermos, and a good Henkel or Zoji keeps it HOT all day.​

They could. I imagine the Zojirushi active heating mug could keep beverages at a fixed temperature with very little power consumption but would probably cost $200.

The real issue is that the really good thermos bottles keep stuff too hot. I found myself making my coffee at 4:00 when I left and the coffee only really being drinkable at 10:00 or even 12:00. So I could either pour it out and drink small amounts from a ceramic cup or just nurse my coffee all day long. Active cooling is possible but generally a lot more energy intensive. The nice thing about the active heating + mediocre thermos design of the ember is that cooling is fast enough (reviews suggest about an hour) to be useful.
