Ember Temperature Control Smart Mug 2, 10 Oz, App-Controlled Heated Coffee Mug with 80 Min Battery Life and Improved Design, (PRODUCT) RED

This mug does everything it promises, keep my coffee hot! Only negative is I wish I would have bought the 14 oz. The 10 oz. Is a little small if you add creamer. I love it!

I purchased the 10 oz. ember coffee cup with the stay warm technology and my daughter was thrilled. However, she did exchange it for their 14 oz. cup. But I still get the credit.

Battery life is about 45 minutes, I expected longer.

Battery dies very quickly I find myself charging it a lot that’s my only issue with it.

I really love this mug, I tend to leave my cup of coffee down and it always gets cold, and would microwave it several times. With the Ember my coffee stays at the right temperature until I'm finished with it. I would have given it five stars however the size is a little deceiving. It stated 10 oz and that is correct, however the 10 oz is at the rim, need to be careful not to spill it, and forget about adding any type of creamer unless it's a literal drop. I would have gotten the larger size but an extr $20 for some extra material is kind of steep. That would bring it To ~$150. Also a lid would have been nice as this is not a cheap mug.
