Very stylish and quality cup. Easy to set up and operate.

If I was going to put a value on this cup I would say fair value should be around $68.99, stays at 140 degrees for around 50 minutes by then have to recharge. The solution is to put a charge base where you would sit more often, by then at $40 a base the cost for drinking hot coffee would exceed what I would pay for this kind of setup.

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.

An interesting, but not necessary device, I never have a cup of coffee sit long enough to get cold, but ny wife does, The cup size could be larger. A bike purchase for folks. Who let their coffee or tea sit for extended periods of time, I am not a fan of the trend of having to use an app for everything (But you can use the mug without the app.)

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.

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.

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.

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

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.

It was a Gift for my wife. She wouldn't part with it now.

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.

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

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.

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 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.

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

Absolutely amazing no more reheating my coffee in microwave

Great mug. Very sleek design and keeps coffee warm.

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.
