Decent cup. Works as advertised. Battery depletes fast when in use however.

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

Let's be honest - the vast majority of people don't need anything like this and it's very expensive for a coffee mug. But I'd be lying if I said I didn't love having it. It's user friendly and just works. Come back an hour later and your coffee is still at that perfect temperature without the burnt flavor you get from other coffee warmers. I do wish it used a wireless charging solution to improve water resistance, and I think a 16-18 oz size would work better. (Note that while it's 14 oz, it's really more like 12 oz of usable space unless you fill it to the brim) It's also worth mentioning that the last few sips can sometimes get much hotter, but that's just because there is so little liquid left so any heat added will jump the temperature more. Not a big deal, but a minor annoyance.

Awesome self regulating mug keeps your warm drinks warm to temp you like for a long time. Well worth it wish it came with two charging coasters. App makes easy setup and pushes out firmware updates to yes a mug.

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 would simply state it works as advertised. The mug keeps your liquid warm down to the last drop. The con for me is the price; a little steep for a mug. Even if it is a smart mug.

Do you hate getting caught up with something, then you go take a sip of your coffee and it’s cold? That no longer happens to me. I LOVE my ember cup, keeps your coffee hot!! And it’s so cool, you get to choose your temperature and mess with the settings through the app to your liking for other beverages as well.

I purchased the mug Feb 2022 for a Valentine’s Day present for my wife. She uses it every morning for her coffee and swears it has been the best thing ever! The only problem we have had with it is charging. You have to make sure it sits perfectly and wait for the flashing red to flash a couple of times. Besides that it still works just as well as the day we got it. If you take care of it and make sure it’s dry before setting on charger you will enjoy it!!!!

My wife loves it! She drinks her coffee slowly and it stays warm!

This mug is amazing! I love that my coffee stays hot without scorching it no matter how long I am distracted from it. My only thing is that the battery life could be better. But for me it's no problem as I have my charging coaster right where I sit in the morning.

This is our fourth ember mug in our collection and we use them daily. The battery lasts a decent amount and being able to set the exact temperature really puts the icing on the cake.

This was a gift and she loved it. The cup keep the coffee warm to her temp. The phone app. is really simple to use. Great buy

When the package says to start at 135°, believe it. The cup and coaster are great for the work-at-homer, it’s not overly large and bulky. The cup has a nice weight to it but, is not to heavy when filled with liquid. Overall, I would purchase this again as a gift

I really like the cup. However, unless you purchase the lid that goes with it, you’re gonna constantly have a film on top of your coffee. Also, the cup doesn’t stay fully charged even when on the charger maybe 80%. but most importantly, it keeps my coffee, hot all day.

Got this as a present for my husband for Christmas. He loves how he can take his time drinking coffee and it will stay hot for a long time. Only thing is you must charge it every night.

Excellent piece of technology. I use mine everyday. The battery doesn’t last too long, maybe 2-3 hrs off the charger. But does what it needs to do and satisfying at that. Works well and very simple.

I like it this mug. Use it everyday. One thing I would point out is, the battery last for one cup. But if you’re in an office. Then it should be fine, since the base is the charger

Got it for my wife for Christmas. She absolutely loves it and uses it every day. The only major problem I see with it is that we are buying more coffee now because she's drinking more and in this economy it's rough. Taxation is theft and the government doesn't care about us. What's even more absurd than this inflation is how they want us all to be in electric vehicles by 2035?! Yeah okay pal that's gonna happen. But anyway great cup!

This is the 5th Ember mug I have purchased, with three of them as gifts. They have all been a hit as gifts and I personally love using mine every day. I am a verrrryyy slow coffee drinker but this keeps your coffee or tea at the perfect temp. It may not heat up liquid from cold, but it will heat up lukewarm liquids to the perfect temperature.

Wife makes the best use of it always having her warm coffee
