Customer Ratings & Reviews

Love the concept and the feel of the mug. But it's unusable due to terrible software. The app has only one star due to issues. I've had mine for 7 months and have had to repair my cup to the app every single time I use it. It was a workaround but I could use it. Now, the app won't even open. I've deleted it and reinstalled it and it still says that the app can't open and to close. I've cleared cookies I've done everything. I've contacted support. So now I have a $120 mug that cools off after a few minutes like a normal mug since I can't use the app and it will not heat without it.

The mug itself works pretty well, although it's battery life is not long. I get about 15 minutes worth of the product working before it indicates it's out of battery. Also, the software is VERY GLITCHY. My app recently stopped working because it stated that a software upgrade was needed. When I clicked to update the software on Google play, nothing happened.

This is a great idea and works well. Please invent a cold one!

Says 14oz. Not sure but do not buy if u use large cup on a Kurieg. Will fill to very top and hard to move or take first sip without spill. No room for cream!!! Good for a person who drinks from a pot. Doesn't last long without being on the coaster. Can't take coaster everywhere u go!!! Started drinking coffee at 7:45 this morning. It's only 9:30 and it no longer heats up. This is after a FULL charge. Not worth $130.

It is a great mug. It is everything I expected it to be.

fabulous recipient raving about it. plan to buy a second one

Sadly, it didn't last a year. Too many email communications back and forth with support. Felt like I got the runaround.

This product is so poor, my handle fell off on the first day, I guess you could say it was not very good. Honestly way overpriced, I would not even take it for $10 and I don't know why I bought this STUPID HORRIBLE product.

Got as a gift, after about a year of occasional use 2-3 times a week for 1 cup, it has difficulty connecting to app. Most importantly for the price, bad and unhelpful customer service so I don't feel it's worth the price.

Don't waste your money. Look at all the better business bureau complaints. Ember did a firmware update that now prevents the mug from working when off the charger. Customer service will initially respond and give you task after task to "fix" it. I think they do this to get you to give up. I provided Ember with great detail of the problem to help them fix it but now they won't even respond.

I drink at least 3 cups of coffee in the morning and like it very warm. This product does not require the cup to be on a pad to stay warm because the battery is in the cup! Once charged it maintains the heat for 90 minutes. Unless you download the instructions to an iPhone, there are no directions. I had to go to Geek Squad to learn how to use.

Tinties, most overpriced piece of garbage ever created. My coffee spills every time I try to fill this mug and the battery life is horrible.

Ember does not support their products. Their support will not get back to you despite claiming to have a warranty. You have been warned that you arr about to spend $100 on something that is likely going to become just a regular coffee mug.

The mug itself is fabulous when it works, however, the charging coaster is defective. Read reviews on Ember's own site. Countless users report that the coaster fails, and the replacements Ember sends also fail within months. Once the manufacturer addresses this production issue I will become a customer again.

Wont bluetooth sync. Tried every method and spend hours trying to get this to work. Fails every time.

This cup was placed in microwave. Y accident and caused a HUGE fire requiring fire department arroval. The cup looked ceramic and it should have been more clear about microwave use, as the cire caused severe damage!

Can't sign in. Whoever developed the app should be taken out and shot.
