    I’ve had my ember 2 mug for a little over a year now and I absolutely love it. It does what it’s supposed to do and it does it reliably. The app is easy and straightforward also. Get the lid to basically double your enjoyment. Instead of a little over an hour of drinking time I get at least 2 hours of hot coffee. I like this mug so much that I bought 2 more as gifts. Seriously my favorite gadget that I get the most use out of.

    Works much better than heating plate. Takes amount of time to heat whole cup so bottom is warmer than top but it works well. Mine only holds 10 oz.

    Definitely go with the 14 oz. I bought the smaller one not realizing the volume. This one is much better! It holds a charge and keeps your coffee hot for hours/days!
