Ember - Temperature Control Smart Mug² - 14 oz - Blue

Let me start off by saying this a one of the best mugs for coffee lovers. With that said, the only two negatives I have to say will be the price and battery life. For the obvious reason, $150 is a little steep for a any mug/cup. It serves a purpose, so there’s not too much I can say. The battery life I wish was a lot better than what you get. It ranges between 2-3 hours. So if you’re someone who likes multiple cups, relaxing and drinking outside, or keeping at your desk while working you’ll definitely have to consider that. The few hours may seem like a lot of time but trust me when I say you’ll get plenty of notifications that your mug needs to recharge, which is slow to do that as well. It may not be perfect but it’s still a great cup.

So far so good! We've had this mug for about 2 weeks now and have used it many times. Drinking coffee throughout the morning is much better!

My husband bought this for me since my coffee always gets cold especially when I am working. I work from home so sometimes I get busy and distracted and I dont get to my coffee quick enough. I wanted the bigger size as that is the type of cup I normally drink. The pros are that is definitely does what it says in keep your coffee warm. You have several different settings within the app to choose from on temp.level. It was extremely easy to hook up to the app and I havent had any issues since. Within the app you can check your battery level. Since I do work from home, I thought it would be best to just keep the cup on the charging pad, but I started noticing that the bottom of the cup started to become discolored. I was a bit worried that it was because I was charging and the heating element were being used too much together, so now I only charge when needed. I dont trust charging it while I am sleeping or gone with that discoloring. I have tried to wash it thinking it could be from something else, but it doesnt not come off. The biggest con is I do not think it keeps a battery life as long as it says. It does seem to lose battery quickly. It is also really hard to make sure it is off just by the press of the button. It seems to light up as soon as you pick it up or move it. The coffee does get an old taste if it has been sitting for a while just like it does in the coffee maker, like over cooked. I was hoping that wouldnt be the case. I use this cup every day during the week that I am working. The rest of the time I use regular cups. I think this would be ideal for someone who doesnt drink their coffee fast or gets distracted easily and comes back to cold coffee often. It is on the heavy side. Definitely bottom heavy as that is where the battery and heating element are. It must be hadn washed and dried quickly. You dont want to leave the bottom wet.

I would give this more like a 3.5 star. It definitely controls the temperature of the liquid you put into it but it does not make it warmer. So just be aware of that. I was expecting the coffee to be just a bit warmer and for longer. So I am not over-the-moon about it. But it is much better than just having your coffee continue to cool. However, I'm not feeling the value for the money. These things are not cheap. And the enamel in the bottom of mine has already started to come off just a bit. Not sure how that happened. I thought it was baked-on coffee, but it's the actual material that's rubbing off the inside of the cup. For $135 for a mug, I would have expected much better quality.

I have had this mug for a couple weeks now but the quality seems solid. The mug itself, feels good in your hand, very solid and easy to clean. The battery seems to last about 1 hour on the highest setting (145 F). But now for the downsides. The App and Bluetooth connection frequently drop. I frequently find myself having to kill the app and reconnect. Which makes this mug really difficult to use. There is no indicator on the mug itself for temperature so when it disconnects from my phone and is no longer heating I have to kill the app, reconnect, and find that my coffee has dropped below the temperature. This has happened about 1 in 3 uses of the mug. Also, updating the firmware was a pain, but hopefully will only have to do that once or maybe twice. Another small issue there is an indicator light... but it is only on the right side. I like to hold my cup in my left hand so I rarely see the indicator. Overall, I would probably not recommend this product and may still return it. If I could just use this mug without an app it would be so nice.

I got this for my husband and he really likes it. It keeps the temperature perfectly, and if he gets busy doing something, the coffee stays hot. He is very pleased.

This is fantastic! I got it as a Christmas present for my Mother and she absolutely LOVES IT! She has always liked her coffee hotter than usual and says this keeps it “piping hot” all day long!

How have I gone this long without this cup!? I am a slow coffee drinker and therefore I’m constantly warming up my coffee in the microwave to get it back up to the temperature I prefer. This cup truly keeps my beverage at the same set temperature long enough for me to enjoy every last drop and at my pace! Love, love, love this cup!
