This is amazing product! Not only does it keep my coffee warm longer it prevents accidents with cats getting too curious about my Ember mug. I wish this was available years ago when I bought my first Ember mug.
Works well to extend the battery life of the Ember mug battery and at least doubles the amount of time coffee is kept hot. However I find drinking from the lid is not as comfortable drinking from the cup itself and not as as pleasing as using covers from other brands such as Yeti.
the lid is really essential to have. If you make lattes, without the lid, the hot milk forms a "scum" on the top and isn't pleasant when you go to drink the coffee; I found it takes 15-20 min. for that to happen. Using the lid also helps "conserve" bettery power; doesn't have to work as hard to keep the drink hot.
I love the new lid for my ember! It makes taking my cup along more convenient
I would recommend this to a friend!

Lid has a serious design flaw that converts this product into a "Dribble Glass". This lid mimics a cup that is sold in novelty stores as a joke. Hot coffee is dribbled down the user's chin. Totally recommend that this product not be used.
No, I would not recommend this to a friend.

Just received my mug lid with high expectancy. Was very disappointed! The lid just sits on top of the mug and does not ‘seat’. It slides right off when I tip the mug to my mouth to take a drink. I actually have to hold the lid on with a finger and coffee still spills out. I ordered the 10 oz lid for a 10 oz mug. A waste of money.
