Got this for my dad for Christmas. Seamless connection to the app and battery lasts a long time.

I got this mug this ember mug for my husband last year for christmas. Retired veteran he loves his coffee. This cup keeps his coffee at the perfect temperature for hours he loves it!

Got this for my step mother for Christmas. Super nice for big coffee drinkers (which she is) she's been using it every day while doing her college work.

I love this mug so much! I tend to take my time drinking my coffee and this helps from my coffee from getting cold and keeps things warm. Such an easy set up as well!

It certainly keeps hot drinks warm, but you have to experiment with choosing the right temperature with the free app to make sure liquids are not so hot they burn. The cup construction is very solid.

I purchased this coffee cup for my Wife as a gift, and she loves it. I bought it for her at a suggestion of another relative, as I would have thought it was too much money for it. But it wound up being a gift she uses daily, and she really likes it. Works well, she uses it for two cups a day, then it appears to need charging anyway.

This was a Christmas gift for my Son in Law. He loves drinking tea during his work day. He is really enjoying this mug and my daughter loves the color!

I like that it keeps the liquid warm for a long time at the temperature of my choosing. It unfortunately has connectivity issues and the app needs to be reloaded to connect.

This is my second Ember cup. Matter fact, I loved mine so much that I knew my husband would enjoy it and this was his Christmas present this year.

We have bought different ones but they alway disappoint, unlike this one my husband is really enjoying it.

Been wanting to get this and glad I decided to finally make the purchase, always tend to leave coffee to get cold now don’t want to worry about it anymore!

It works but needs a charge constantly. Therefore i think its overpriced.

Great dor 1-2 cups, but on/off gets tedious after an hour or so. Otherwesie, great.

only downside is that the cup stains after awhile, so I exchanged for the darker color and no more problem. keeps coffee perfect temp to the last sip. I use it daily

Didn’t think I would enjoy using this cup but it truly keep your coffee hot from the moment your pour your coffee to this cup until hours later

Ember mug works great & keeps liquid desired temperature. but occasionally mug doesn’t connect to phone/app. That’s the only reason I gave it a 4. I believe it is a app or technology update issue however.

Great mug. Works to keep coffee at 135 deg or your preference. Before I had to run to the microwave multiple times to keep my coffee hot. I like to slowly enjoy my coffee. Since Starbucks will not allow thermal mugs anymore, this replaces that and better. Enjoy your coffee 100%

I really wanted to like this mug and it's possible I got a defective one but after only 4 charges, it was not charging properly. One of the small pins on the base of the charger was not working properly. No water was ever near it, so it was a bummer for sure. I ended up getting a mug from another company and it's been great.

Great mug, keep my coffee at just the right temperature for a long time. Awesome capacity.

I bought this item for my wife. She absolutely loves it. She loves the shape of the cup and the fact it's not heavy considering the technology. Her favorite function is that she can control the temperature from her phone app.
