I'm writing this for a chance to win a $400 gift card lol Cool cup, though

It’s my second mug. I like them but battery time is limited to one cup.

Pros: Does keep your beverage hot for a good hour. Cons: Bluetooth connection drops all the time. Have the biggest mug yet still feels like not enough compared to normal mugs. Need to wash immediate after use and put on charger so it's ready for next use.

Great buy! Keeps coffee at perfect temp, throughout drinking it!

The mug does an excellent job at keeping the coffee warm. The app is a bit finicky and needs to be updated.

Love my Ember mug! my coffee is always hot! Never again will i drink luke warm coffee!

I've always enjoyed coffee, but I don't like it too hot, and I don't like it too cold. First world problems, I know. However, my Ember cup has changed my world. I make a cup, wait until it reaches my set temperature (128), and then start sipping it. Amazingly, my coffee remains at 128 degrees from that first sip until the last one. If Maxwell House had not already used the phrase, "good to the last drop", then I would apply it to Ember, which would be more true. This thing is worth it!

Worth it if you drink a lot of coffee. I no longer need to chug it down quickly to enjoy it hot.

I love this cup and have needed this my whole life!! I love my coffee but i get busy in the morning and sometimes leave my cup for 20 minutes at a time, coming back to not so hot coffee.. I love hot coffee and the Ember provides that hot that I love.

Bought this as a gift for my spouse. I was highly skeptical but she really likes it. Its great for anyone who takes longer to drink the coffee or tea. The best feature however is the one that tells you your coffee is at the perfect temp. No more burning your mouth then setting it down to cool and forgetting about it and coming back to cold coffee.

This mug does exactly what it’s supposed to do! Just keep in mind that the mug works even better with a lid which will help maintain a uniform temp, otherwise the Mug will cool a little if you’re in a cold environment. I purchased a universal mug from Amazon since it’s virtually impossible to get an ember one. For the price, you would think a lid would be included.

I like to drink my coffee hot, and my 14 ounce temperature control mug keeps it perfect for me!

I love this Mug so much, I've purchased 3 of them over the past two years (2 for me; 1 as a Gift). If you take hours to drink your hot beverages, do not hesitate to purchase this. While I wish the Battery would last longer (approximately 70-80 minutes for preferred temp of 145 degrees), I can't complain about anything else. Looks great next to my Starbucks Verismo machine as well.

I love this mug. I drink coffee slowly at my desk so it keeps it hot in between sips!

Great mug and does the job, just wish the battery lasted a bit longer.

i LOVE this mug! When I bought it, on sale on a app drop, I still thought it was an excessive purchase, but I am amazed. I love this and use it every day

Bought this for my wife as valentine's day gift. We are very picky on our coffee in terms of the process its made and freshness so we usually make our own coffee at home. Using this cup has elevated the flavor since it retains heat for the duration of the drink. I want to buy another one but the price for it went up from $150-180. Got to wait for a sale on this...

Awesome job of keeping coffee hot - just expensive

Works very well but the price is quite high. Keeps liquids at temperatures I like.

Never knew I needed this. My husband complained we were wasting money because I used to only drink a half a cup of coffee when my coffee went cold. We use Nespresso vertuo capsules. Not cheap. However, he bought me this as one of my gifts for Christmas. But we’re not really saving money because now I drink two full cups of coffee a day. But hey at least I’m not wasting money!
