Customer Ratings & Reviews

The battery tends to not last very long. I would like it even more if there was a percentage on how long the battery has left and what the temperature is on the cup.

Very pleased with this produce as it kept drink to perfect temp for over an hour along with having the cup on its charging station. Just love it.

I have wanted one for many years now and finally got one. Great for sippin on tea or coffee throughout the day!

Great cup that keeps my drinks warm just the way I like it. Very comfortable to hold and would definitely reccomend

The quality of the product is very good. Perfect gift for those people who want their coffee to stay hot all the time.

I love the mug. I can do something for a little bit and then when I come back to my mug, it’s still warm !!! Definitely would recommend

I love this cup !!! Once you have one you won’t ever want to be without one!! This is my 5th cup they make great gifts.

After less than two months of ownership, the copper finish is coming off on the inside. This is NOT dried up coffee it is actually the finish slowly coming off. I use it on average 5 out of 7 days per week and clean it with a sponge. I am now drinking copper infused coffee. Eawww. I am past the return policy but I plan on getting reimbursed or given another mug in a finish that won't come off.

Keeps hot coffee and tea at the temperature you set it too! Always hot ! Great product!

I really like that this mug is metal. It keeps a good consistent temperature. I looooove having this mug.

Gave this as a gift after having bought one for myself. The recipient loved it.

Easy to use and works well. The only complaint is that the battery doesn't last long and it's doesn't keep your drink warm while charging.

My Wife now wants all her coffee mugs to keep their temperature like this mug can. I really wish it could be dishwasher safe, but it's a small sacrifice for the luxury of having perfect temp coffee for hours at a time.

Great gift for family! My mom had surgery and is stuck on the couch, so keeping coffee warm has been amazing!

The fit and finish of the copper Ember coffee cup is first rate! This cup connected to my phone easily and keeps temperature well. I got it for my cabin so I can have warm coffee at the campfire. I am happy with this cup.

Always have my coffee and/or tea warm whenever I need it! Also a great gift to give/get!!

I bought this for my Wife and she loves it. She uses it everyday. She said it keeps her coffee warm for hours.

This works really good! Heats up pretty quickly and keeps my drinks at a personalized temperature.

I’ve gotten these as gifts multiples times, both the mug and the travel mug. Everyone that gets them seems to love them and say it works great

With my wife working from him this has been great it keeps her coffee warm till she is finished with it. Never again having to make another cup because you forgot about it because it keeps it at a great drinking temperature
