I love the look of these mugs and used them for a couple years, but we've had issues with them breaking when hot coffee or water is added. We ended up getting rid of them because it was too much of a risk that someone would get burned or cut.
Thank you for your review, Shari! To reduce thermal shock, always pre-heat the glass first. You can also insert a metal spoon in the glass when pouring hot liquids in to disperse the heat further.
