Works EXACTLY like shown
I work around kids so my water bottles and mugs were constantly getting banged around and knocked over. I saw an add for this and decided to try it. After 2 days, I ordered another case of 3. They work AMAZINGLY for keeping drinks their right temp, the spill-proof lid is legit (it NEVER spills in my purse or gym bag, even just thrown in), and it seriously does NOT fall over.... even when toddlers bang into it while playing. I cannot get enough of this mug. That only one I'll use from now on!
