Customer Ratings & Reviews

There is nothing like a nice cup of coffee - no matter how long it takes me to drink it! The app to manage the cup and its temperature is very easy to use, and the battery lasts about 80 minutes on a full charge. It's more than a nice to have, it's a must-have!

I bought it as a gift for my wife. She loves it. It keeps her coffee at a nice temperature.

This is great. I used to drink my coffee fast. Or I’d get distracted and have cold coffee, Now I’m not in a rush to drink it, and if I get distracted for a bit, it’s still warm for me!

Can't live without it for my morning joe. Keeps it hot while I sip and read the news.

There's nothing quite like going back for another sip of my coffee that I made 30 minutes ago and have it still be at the perfect temperature. I've had this for about a year now and I am in love. You can't go wrong with an Ember mug or tumbler

I like it. It keeps my coffee, warm and cold weather.

Before my Ember mug, I used to have to reheat my coffee in the microwave -- sometimes more than once. No more! I love the comfort of warm drinkable coffee, and this allows me to set it just how I like it, and keep it that way while I'm working and sipping on it. I'm going to buy a second one for the office.

I wish I knew about this along time ago. This keeps my coffee warm at the temperature I set on my phone app. The secret benefit is that it warms up my coffee after putting cold milk in it. My only wish, besides a longer charge, is a larger 16 or 20 oz size. A 14 oz mug means 14 oz without the milk, syrups, etc.

Always wanted one but too pricey. Got it half off and love it. I want another one.

I really like the cup. However, unless you purchase the lid that goes with it, you’re gonna constantly have a film on top of your coffee. Also, the cup doesn’t stay fully charged even when on the charger maybe 80%. but most importantly, it keeps my coffee, hot all day.

Easy to hold, maintains perfect temperature for 3 hours with the Ember lid accessory.

Christmas present for wife and she loves it. Keeps coffee warm during entire workday. App is a little useless but fun to control. This does include a charging pad. Hand wash safe too. Definitely go with the larger oz size if the price is right, 10 oz is not enough these winter days in northern Wisconsin.

Perfect gadget for hot drinks! The standard temp without using app is 135deg which is okay temperature to keep your drinks warm but when using the app, max temp of 145deg is perfect! While on the dock it keeps the drink warm all day, when off the dock 70min? Perfect gadget for cold office! Highly recommended

Love using this cup, give me perfect temperature with tea

I had this product for about a week and it works great, but make sure to tell your wife not to put in microwave. It will melt quickly.

works as advertised, perfect during the cold months to keep the coffee warmer a littler longer!

I bought this for my wife, who is a coffee drinker. She loves it. She usually nurses her coffee and consequently had to microwave it a couple of times before finishing a cup, but not with the Ember. It keeps it nice and hot all the time.

My second Ember mug and this one didn’t disappoint. Simple to set up and connect to my Apple iPhone. Keeps beverages a set temperature without a struggle. No more throwing away cold coffee or needing a “hot top”. Worth the price.

I bought one of these for my friend because I couldn't justify spending this much on a cup. He praised it and so I bought one for myself. I used it for 2 days and now it's in a storage box in the garage. Reasons follow: 1. It doesn't hold enough coffee. Yes, it's 14oz, but nobody is going to fill it to the brim, so it really only holds like 12oz of coffee. My usual morning coffee is about 16oz, so that's already a problem. 2. It doesn't keep the coffee warm long enough. Yes, I know, a small battery can only do so much, but seeing how it only keeps the coffee warm for 1-2 hours (as far as I remember), you're better off sticking a lid on top of your coffee mug to help with insulation or just using a regular mug with a hot plate / mug warmer. Sorry Ember, I wanted to like this cup, but it's not practical enough.

Works like it is advertized. Keeps the liquid hot for a long time
