Customer Ratings & Reviews

I am really enjoying this mug, as it keeps my coffee warm. Plus, the mug and coaster look lovely on my desk.

This stylish mug keeps coffee at the perfect temperature! Only downfall- we need a second base so the mug can go to the office and stay charged so we don’t need to haul the base from home to use it!

As an office worker, this product is a must. Keeps my coffee warm all day!

Bought this for my wife and sister in law, who are both avid tea/coffee drinkers. Both women are always busy with life and careers and this makes it easy for them to enjoy a nice warm/hot cup of their preferred drink of choice daily. Very easy to manage and control via the app and battery holds up very well so far. From my interactions with them, they don't really have any major complaints.

I put this under a "I never knew I wanted one" category. I bought it on a whim because I had some rewards saved up and decided something frivolous might be good. I really only like hot coffee so tend to guzzle it before it even gets warm. This does exactly as advertised, keeps it hot. So I find myself sipping not guzzling.

Had the original Ember mug which was a game changer for a heavy coffee drinker like me. Only complaint for the prior version was the coating which eventually started peeling, which is why I purchased a new one as a replacement. Now with the bare metal design, this peeling no longer an issue. Bought one for myself and one as a gift. No regrets.

I got this mug as a gift for my dad and he absolutely loves it. It does a great job at keeping his coffee warm. The only thing I would change is that I wish it could come with a lid to make it easier to carry when full of hot liquid.

This is a great mug, it keeps my coffee nice and toasty. The only reason it’s not a 5 star is even though it says it has an hour and half battery life that doesn’t seem to be the case, the battery will last maybe 20 minutes. About the time it take for me to drink a cup. I’ll drink a cup and then go to get another cup and it says it has low battery and I’ll have to charge it.

honestly a very neat way to keep your hot liquid nice and warm for a while. Sadly the only downside is the fact that the battery life seems to dwindle more and more after uses. It dies faster than I can finish my 2-3 cup. Impressive yes but i like to enjoy my coffee. Not drink it quick. Over all, an interesting item.

Bought this for my coffee drinker husband. He loves morning coffee but drinks it really slowly. Often 3/4 or 1/2 his coffee was wasted as he didn't want to reheat it over and over to finish it. Now he has enough time to finish the whole cup and he gets to enjoy it at the exact temperature he'd prefer. Only down side is that it is hand wash only, which is obvious since it essentially plugs in.

This is everything that it says it is this cup is so amazing keeps everything warm and I loved it so much that I gave them as gifts at the office

Love it and use it daily. Perfect solution for keeping coffee hot at the desk. I get so busy and sidetracked at times, its great that it keep it my favorite temp during my busy moments.

Bought this again wore the first one out after 5 years pretty good life so this time I got the stainless !!!

Works as is. Easy to use app. A bit pricey though for 10ml mug.

After buying countless cup warmers from various companies, which never really worked, i was happy to see something like this. Works as intended. My coffee never gets cold. Definitely worth the money

Great mug. Very sleek design and keeps coffee warm.

Bought this as a present for my mom for the holidays and she's over the moon for it. Keeps her coffee the perfect temperature for hours off the base and all day on it. Great product.

I love this. I'm a slow coffee drinker and frequently my coffee would get cold by the time I finish my cup. This solves the problem for me and is near perfect. The only issue is that it takes a long time to recharge. Oh, and the cost is ridiculous. However, I'm a sucker for items that solve life's little annoyances.

Maintains a fairly accurate temperature the size is not too big and bulky. It’s a little pricey, however

This is a wonderful item for someone who enjoys slowly sipping coffee or any warm drink. Easy to set temperature, and works plenty long enough even if not sitting on charging pad.
