Customer Ratings & Reviews

This mug is simply the best- it hears up as soon as yoy put loquid in it and it keeps it at the preset temperature- simple as that.

I am not the best person to write a review since I’m not an avid coffee/hot tea drinker. Even with that said I think the mug is great. It even makes for a good cup of oatmeal (I tried it this morning) The only downside is that I didn’t get the larger one.

Convenience, quality, and class all in one glass. Have loved this mug and can’t help but absolutely love the temperature control. A must.

I received this travel mug for Christmas 2024. Within 3 weeks of use the charging coaster would not charge. Customer Service is extremely poor. Emails failed to resolve the problem. It is hard to find a phone number to call. In addition, the battery does not last long off the coaster.

Grat coffee cup Keeps my coffee nice and hot , just the way I like it.

Nice sized cup and feels good to hold, keeps my coffee hot!

Keeps the coffee nice warm. Only wish the charge would last longer when cup is not on the charger plate.

My wife got me and EMber mug that was given to her as a promotional item. I thought what a waste. And then I tried it - I absolutely love it.

My husband loves this cup. I bought it as a Christmas gift for him this year and he has been enjoying it ever since. The perfect cup...The perfect gift!

Works great. I use it every morning for my coffee and it keeps is warm all morning

I received this mug for a Christmas gift from my husband. I absolutely love it! Keeps my beverage just the right temp to the last drop. I highly recommend this product.

Excellent mug, only wish I had purchased the bigger size.

I LOVE this product!! I’m at the end of my tea and it’s still so hot! It’s like having the first sip all over again!

Keep my coffee 140 perfectly. I use it every morning.

Great idea but the mug and company are horrible with customer service. First off received this mug as a gift. Had issues from the get go with having a stable connection. Read the instructions, watched tutorials and jumped on forums to troubleshoot and still nothing worked. Took a real deep dive by going to the company website and found out that my phone, Pixel 5 Android OS wasn't a "compatible" device but other current phones were. Reached out to customer service got the same response but was told that the mug would work without the need of an app so gave that a try. Well after a day it held a consistent temp but after it started to lose power it just reset itself and had to reinstall the app and connect it to my phone once more to reestablish the preset temp. Tried returning it after 18 days and my fiancé was denied since the return window passed. If you really want this mug do your homework because it doesnt work with all Android phones but if you're an iPhone user you're in luck because surprisingly all of their phones work.

Works as advertised, verry happy with the purchase.

This is a great idea, but what you actually get is a terrible product. First of all, the battery life is terrible and the charge time is to. Secondly, connectivity issues left and right with the app. Third, it says my mug is empty when it's not, so it stops warming despite having battery left. An insulated travel mug keeps the coffee hotter, for longer, for a fraction of the price. Even a plain ceramic mug keeps my coffee hot for longer than this.

It only goes up to 145, which is ok, but I like my coffee at 155 - 160. The battery only lasts an hour or so unless you keep it on the charger. The cup has no insulation so beverages go cold very quickly. Overall, it works but not for a serious all day coffee fiend like me.

They are hit and miss, bought multiple ones and one works to this day and another stopped after 6 months, another had to return within weeks.

I purchased this mug two and a half years ago, another one for my wife. Mi mug is chipping on the inside, I have no idea what I am ingesting. My wife’s stopped working, the app reads 84% battery, but does not keep it hot or warm, it just goes downhill unless it is sitting on the charging cradle. I contacted Ember, they replied they needed the serial number, I sent a picture of it, they then stopped communicating with me. For this price the mug should last substantially longer. I will switch to a different brand.
