Review on GROSCHE Cyprus Double Heatproof Insulating by Erik Haynes

This is the best double wall borosilicate mug we've found (we've tried 6 brands). The 16 ounce size is large (bigger than similar brands), the handle has a hole big enough for big hands, but the handle itself is narrow, which is comfortable for small hands. They don't tip over easily. The style is elegant. Unlike others, we didn't find them fragile. Will not crack or chip with normal use in boiling water and microwave for up to 3 minutes. We didn't drop any so I'm not sure if they will break. We wash all the dishes by hand, but we don't handle them very carefully, other dishes accumulate on top of them, and although it looks delicate, it doesn't behave delicately. We gifted it to a few friends and they love it too.
