I was surprised that this mug works so well! It’s very lightweight and easy to store in a small spot. The cord is just the right length. The base is small around the size of a tape roll which is perfect for those small spaces. The mug has a bit of weight added to it but not surprisingly a whole lot. It’s easy to keep my coffee warm at the perfect temperature. It’s super easy to adjust the temperature to my liking. My only 2 bad feedbacks is the mug lid comes off so easily which isn’t something I like. The same goes for the base. I wish it could like click in. Otherwise this is such a great mug. I use it outside while giving out school grab and go meals and sometimes it’s so cold outside by the time you have a chance to drink your warm drink it’s cold by then and reheating it isn’t the same.
