The double wall really does keep my coffee hot way longer than my old mug, and I don't have to worry about burning my fingers on the outside. Being able to actually see the coffee through the glass is a small thing but it genuinely makes my morning cup more enjoyable.

Watching the coffee swirl around in that double wall gap never gets old, and it actually keeps my second cup warm for way longer than my old mug did. The glass feels sturdy too, not as fragile as I worried it'd be.

I didn't expect to care this much about seeing my coffee through the glass, but watching the crema swirl around in the double wall is honestly the best part of my morning now. It keeps my latte warm way longer than my old ceramic mug too.
