    I had this product for about a week and it works great, but make sure to tell your wife not to put in microwave. It will melt quickly.

    Dare I say you should not buy one of these ember coffee mugs? why would I say that? Because I am drinking so much coffee it is pouring out my ears! When I had the old style coaster heater it took me 45 minutes to drink a cup of coffee. The temperature fluctuated to too hot to not hot enough but it stopped the coffee from getting cold. My coffee is so utterly delicious that I am now drinking, since I used it the last two days, twice as much coffee each day as I usually do. This mug is absolutely AMAZING! Buy one for yourself at your own risk!!!!!

    14oz is the way to go. No more having to go back and top off the cup just to keep your coffee warm. Stays at the temp you set all the way to the last drop.

    I love drinking hot coffee, and this mug made it perfect to drink hot coffee and teas. I don't drink coffee too fast, and regular mug cools it down fast before I even get to finish the coffee. However, this cup made a huge difference. It's easy to setup and use!

    Worth every penny! Would recommend for all my fellow neurodivergents out there that have taken a sip of coffee only to realise it’s been cold for 20mins whilst you’ve been doomscrolling on the socials. Buying another one for the wife!

    I bought the 14 oz Ember - Temperature Control Smart Mug² myself and then six more as gifts for my family for Christmas and Birthday presents. They are amazing! Everyone raves about their mugs. Your coffee and tea will stay totally fresh and hot. There is no product on the market that compares to the quality of Ember. Will get the travel mug next!

    As i was in my nook reading a book i took a sip of my coffee. As it moistened my lips with a great chill i knew i needed to find the perfect solution to keeping my coffee always at 125 degrees. I thought to myself, hey my microwave can do that. But nay, i am not a mere peasant and thought out of the box. In fact my thoughts took me to a giant box called Best Buy where i was directed to this beautiful device.

    Since my family got me one of these for Father's Day a couple years ago I can't use anything else. I usually drink coffer throughout the day, and I nurse it. That normally means cold coffee, but this thing is the answer to that, My only complaint is that the battery doesn't last that long (keep a charge plat near) and if you use metal spoons to stir you will damage the ceramic coating on the cup. I have gone through three of these now, but I won't live without it.

    We love these mugs. My wife has one and I’ve purchased one for several friends for birthdays, etc. We haven’t gotten to test this individual mug out yet, because it’s a gift for someone in October. But if it’s anything like the other ones, we will love it.

    I bought this mug for my boyfriend for Christmas and I use it just as much as he does. It’s perfect for the colder months. Definitely keeps my beverages warm and get this, if my coffee has been in the French press for longer it reheats the coffee as well. Definitely buy it!

    These e-cups are wonderful but they will spoil you. Unless I have my e-cup, nothing ever stays warm anymore.
