Purchased as a gift and my friend loved it! Especially the color and as an avid tea drinker, he can't get enough of it. I did purchase this on sale so not sure if the color of the mug matters.

The mug does exactly as advertised. I get about 1.25 hrs of usage out of this using the max temperature ( I like it uncomfortably hot). App has connectivity issues but can be fixed in future updates.

Hi Alex, thanks for leaving a review here! We hope you can still enjoy your Ember and appreciate the feedback. The 14oz Ember has an expected battery life of up to 80 minutes, but this can vary dramatically depending on a few different factors. We do want to assure you that the mug is functional without connection to the device, but if you're still experiencing issues, please reach out to us at [email protected] - we'd be happy to help!

Keeps my drink warm. Few quirks with the 1 hour battery life. White color also has coffee stains and burner stains at the bottom. Still works great after 6 months.

Bought for my wife as a gift. She loves it! Now coffee is still warm on the mornings the kids make it impossible to drink it immediately.

My wife loves her coffee and she loves it hot. At first we were skeptical but it does the job and does it well. Her last sips are as hot as the first ones making the entire cup enjoyable. We bought the white version and there is noticeable staining after some time. I’m not sure this will last forever like a regular mug but a great concept and performs well. The price tag could be less but if hot coffee or beverage is important to you to the last sip this is a must have.

Love this mug! Gave it to my sister for her birthday and she turned around and gave me one for mine. I absolutely love it. I like my coffee hot and really enjoy not having to drink it quick before it gets cold as I have had to do since I started drinking coffee 50 years ago! Nothing like a leisurely cup while reading. The 14 oz mug gives you enough room to add cream. Initially my sister gave me the 10 oz which I found to small.

Bought as a gift for girlfriend because she likes her coffee super hot. This goes up to 160 degrees (i think).
The battery does not last long on the highest setting, so you always have to put on the charging base while using.

I've only had this mug for three weeks, but so far it works really well. Better than I expected. We'll see how long it lasts. I like that the cup recharges very quickly. The app to control the temperature seems to be easy enough to use. I only gave it four stars because I don't know yet how long it is going to keep working. So far though, it's been really great.

 This mug is the Cadillac of heated mugs if you add the lid, it’s the best of the best doubles the time your coffee will stay piping hot when you put the lid on and you sip out of it it’s smooth sailing not like other mugs where you gulping simply the best. Add in that you can run it all from your smart phone on your iPad and customize everything. Wow, happy happy

I have been wanting this mug for a year but didn’t love the price. My husband surprised me with it and I was over the moon. I love the sleek design and the app. I will say the charge on the mug doesn’t hold that long (for someone who needs a mug like this, it’s because you get busy and don’t have time to drink when hot)
The biggest issue is that because I use a little milk in my coffee the cup essentially cooks the coffee whole time which led to a skin of coffee/milk forming on the top. I returned it.

I have been using one of these terrific mugs at home for over a year. Once you have had one it is difficult to live without, hence this new one for the office. This ingenious product delivers exactly as promised keeping your tea or coffee at exactly the preselected temperature for over an hour off the base and indefinitely on the base. I thoroughly recommend it.
