Customer Ratings & Reviews

very nice product! easy to use and does the job well! Stays hot long after the product has started.

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

Great buy! Keeps coffee at perfect temp, throughout drinking it!

Love my Ember mug! my coffee is always hot! Never again will i drink luke warm coffee!

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.

Worth it if you drink a lot of coffee. I no longer need to chug it down quickly to enjoy it hot.

Great mug and does the job, just wish the battery lasted a bit longer.

Privileged. Did I need it? I didn’t think so until it was gifted to me. I use it daily. It works perfectly. Between working from home and taking care of two kids, my coffee would frequently get cold due to distractions. This mug is the answer. No more microwave trips for cold coffee.

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.

i LOVE this mug! When I bought it, on sale on a app drop, I still thought it was an excessive purchase, but I am amazed. I love this and use it every day

I love this mug. I wasn't sure if I was splurging a bit on an unnecessary item, but I have fallen in love with this mug and use it daily. No more cold beverages becuase I was distracted or forgot about it for a few minutes.

I like to drink my coffee hot, and my 14 ounce temperature control mug keeps it perfect for me!

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.

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

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 mug. I drink coffee slowly at my desk so it keeps it hot in between sips!

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.

Ember cup is super. Keeps my coffee warm all morning. Couldn't live without it.

Bought as gift for wife and I’ve heard nothing but great things about this product. She loves the fact she can control the temp from the palm of her hand and don’t have to worry about other means to keep it warm.

Works great! Keeps my coffee or green tea at exactly the temperature that I prefer for the 60 to 90 minutes that I sometimes need to drink the full cup.
