Work great but after a couple week tge small prongs that sit on the charger stopped popping out so it stopped charging

Boxes for my daughter because he makes her coffee and then she gets doing stuff and then her coffee she dumps it out she's only had two sips out of it now she can finish her coffee keeps it hot

Love this mug use it every day I would highly recommend

Love that it keeps my beverages warm. Easy to use and keep clean.

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.

It was a great gift! Keeps everything warm and is very easy to use.

[Employee of bestbuy] I would not consider living a life without this thing. We drink coffee every morning and drink tea once per week. You know how it sucks when hot beverages start to go cold? Welp for $150 you never have to experience that again!

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

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.

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.

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!!

Worked great for about 6 months! It started not charging the mug would only charge sometimes other times it would say charged then would just shut off.

Keeps coffee at the correct temperature. Battery life is a bit shorter than desired, but if on the charger it works for multiple cups throughout the day. Good investment.

This cup works great and greatly increases the pleasure of a hot cup of coffee.

Great cup. Works extremely well. It’s too bad the price keeps jumping around

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

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

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.

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

It's a completely unnecessary product and far more expensive than it's worth, but still, I use it every day and love it. It takes me a while to get through my daily hot beverage and either poured out the last bit or just took a big swig to finish off the cold remains...but with this my drink stays the exact temperature I want down to the last drop. The 14oz is a little inconsistent in the temperature sometimes...the bottom of the cup can have the liquid a higher temperature than the top depending on how long your drink has been sitting. It's a big mug and exposure at the top since it isn't sealed seems right.
