Customer Ratings & Reviews

Honestly, it is one of the best items I have ever purchased. I don't think I will ever go with out this mug again.

Keeps my coffee hot and fresh. I love the ease of use as well!

Bought this for a family member and he was super happy! Keeps coffee/drink very warm even after a while!

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.

Great product. Definitely keypad the perfect temp. Battery could last longer for the price.

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.

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.

These e-cups are wonderful but they will spoil you. Unless I have my e-cup, nothing ever stays warm anymore.

Wife makes the best use of it always having her warm coffee

Amazing, high tech cup! Meets all expectations and extremely useful.

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

I love this cup and have needed this my whole life!! I love my coffee but i get busy in the morning and sometimes leave my cup for 20 minutes at a time, coming back to not so hot coffee.. I love hot coffee and the Ember provides that hot that I love.

I was feeling ridiculous about buying a temperature controlled mug; turns out it was just what I wanted.

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.

This just works. Coffee stays hot, no temperature fluctuations. It feels solid and has a nice weight. I invested a little more and bought a second charging coaster so I can easily move from room to room. Is this a ridiculous price for a coffee cup? Yes, it is. Is it worth it? Yes, it is

Easy too used products really nice I liked that recommended

I love this cup. I have my hot coffee through my one hour and a half of study every morning I’ve bought through two others and I’m considering buying more for all the people I love.

This mug is great. Now my wife or I can have our coffee and chase our kiddos around without worrying about drinking cold coffee. Keeps the coffee hot for over an hour.
