Customer Ratings & Reviews

I love, love, love this cup. I can't tell you how many times I get pulled away, come back and my coffe is cold. I decided to buy this cup and I do not regret it. I can come back an hout later and my coffe is just as hot as the first sip. I nolonger am throwing out 1/2 cup of coffee. Loved it so much bought one for my Sister - she loves it jst as much!!

Bought this as a holiday present for my husband and he uses it everyday. It’s been over a year and he still loves it!

I love this cup, my drinks stay at whatever temperature I set for the entire cup down to the last drop!!! This is an excellent gift idea for anyone.

I am always complaining because my coffee gets cold before I can drink it. My new Ember mug has changed all of this. I customized my coffee’s temp and it suits me perfectly. Best investment and gift I have had for a long time. So happy with this product!

Very good product and works great, easy to use and worth the money for any one who would like to enjoy their drink for a longer time, or someone who has a lot of multitasking

Works excellently! Love the black. It made us want another one.

Keeps the coffee hot all morning long. Great quality and the charge lasts plenty long.

Bought this as a Christmas present for my wife. It has performed perfectly for her in about a dozen uses thus far. This size is definitely worth it over the 10oz option. It is expensive for a cup, yes, but a wonderful way to keep hot drinks at the perfect temperature. I was able to get it on sale at $100, and that's the price I would wait for again.

I brought this for Christmas for my coworker/friend. She drinks tea throughout our whole shift. Our office area is constantly cool where she has to repeatedly rewarm her tea. I thought this would make the perfect gift. She uses it daily and love that her drink stays at the temp she like. Additional bonus is it works with an app on her phone.

My wife has a home office set up with a mini fridge and coffee maker, and when she’s home working, she spends hours on video conferences, and when I happened to drop in on her, I noticed her coffee was often left sitting on her desk partially full. I know she likes hot coffee so I surprised her with this so her coffee will always be hot, and she is thrilled with the results, saying she never realized how much she missed having a hot cup of coffee during the day.

Ember works well. Maintains a consistent temperature. Only complaint would be regarding the length of time the cup is able to do so.

Nice product. Keeps coffee hot as advertised. I thought the battery would last longer though. It only lasts an hour, maybe a bit longer. Overall I am happy with the product.

Works wonderfully and keeps temperature . Love how you can sync it to your phone and have it set at a certain time of day and your beverage be ready for when you're ready to be on the go.

Love using this cup, give me perfect temperature with tea

Ordered the blue Ember mug online. Shipping only took a couple days. It works well. The app is easy to use. Having hot coffee or tea from start to finish is fantastic!

Always keeps my cup to the perfect temp. App is easy to use and simple simple sjmlle. Highly recommend.0

So far so good. Wish the maximum temperature could be set to 155 as 145 is just about warm for my taste. I was debating between 10 and 14 oz due to additional cost. But ended up going for 14 oz and glad that I did. 10 oz would have been too small and require frequent refill. You might as well heat in the microwave on refill visit. 14 oz also carries perfect amount of heft and feel. You know you are holding something good with or without your tea or cofee. That said, be careful while washing (handwash only) as the contact points (the two circular rings) with charging coaster are visible and exposed.

Great cup, it has a few quirks about charging and knowing when to charge it. The app has a few issues though.

Works great. A bit pricey but it was a gift. Keeps coffee hot!

If you love coffee, you need one of these! It is fantastic! By far the best gift I've ever had. It surprised me how much I love this new cup. Not only does my coffee not get cold as I move around the house, even when I'm using it at my desk keeping it on the charger, this cup let's me enjoy that cup even more. All the typical changes in temperature you don't even realize you've gotten used to in a cup of coffee are just gone. I promise you'll love it.
