The design of this mug is sleek and attractive. I just toss it in my bag and it stays sealed. No leaks after being tossed around. My drink stays cold for hours and it’s easy to drink from.
The only negative thing I have to say, is that all the packaging/ directions are in a foreign language. Not that I need need directions for a mug, but I’d like to know the benefits/features- English would be nice.
