Ember - Temperature Control Smart Mug- 14 oz - Black

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.

This is my second ember mug, and it's all i use. It keeps temperature for well over an hour and i can use it several times a day as it charges pretty fast! The sturdy, weighted bottom and the width of the handle make it the perfect cup

Keeps my nespresso hot and fresh all day while working from home or in the office. Bought this on sale for $50 and highly recommend buying at this price. Knocked out one star because if the cup is at highest heat setting, it will drain the battery in less than an hour. Not great for traveling but just fine if the base plate is nearby.

This is an amazing little coffee mug. I have been waiting for like twenty years for someone to come out with a dependable self-warming coffee mug that actually worked and kept your coffee HOT. I mean steam comes off the coffee the entire time (I have mine set for 145 degrees (max). I will opt for the optional lid, too....as it makes it great to take on hikes, in the car, etc...not to mention it saves on the battery because it stays hot easier. At $99 sale price, it's still pricey, but honestly, I'd buy one again if need be. Bonus: I love the dark blue color, which was the only one on "Deal of the Day". Win win!!

Love my ember mug. Keeps my coffee hot for hours. I like the larger size and the handle.

Keeps coffee at correct temperature for about an hour depending on how high. I wish the battery lasted a little longer, but it’s usually okay. The inside of the white mug is already staining after about a month if use.

So I was super excited to get this! I just had a baby and my husband would leave my coffee on my nightstand and sometimes when I’d wake up, it was cold. When I came across the Ember I was stoked! Come to find out that the battery lasts like an hour. I did, however find a solution which is to leave the charging station by my nightstand some it’ll remain charging while on it!! So now I can wake up and have my coffee at my favorite temperature!! I love that I can control it through my phone and it alerts me when it’s reached my temperature and when it’s low on battery. You can also choose a light color, kinda like a mood ring!

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.

My sister purchased me one as a gift - it is incredible! If you like user friendly tech, this is your new coffee mug. I like to take my time drinking my coffee and am often interrupted, my coffee stays perfect! Never a burnt flavor or old taste - simply perfect. The plate stand charges the mug, the mug holds a charge, the mug will keep the beverage can be moved about an maintain the temperature. Also, temperture can be customized. Not for the dishwasher and no metal spoons for stirring - will cause etching on coating.
