[This review was collected as part of a promotion.] There are so many things I love about this mug. It’s design is beautiful and it’s easy to hold. It keeps my coffee hot until I finish it (which is a feat since I have two young kids and I’m always forgetting about my coffee and coming back to it later), but at the same time the other wall stays cool so I don’t burn my hand. Finally, I LOVE that it’s glass, because it gets super clean (no coffee rings at the bottom after washing). It’s a must buy.
