The positive is that they are beautiful and elegant mugs, and I have 3 sets in different colors, and change usage depending on the occasion or season.The negative is that the handle gets cracked off too easily. I try to hand wash them to prevent this but still manages to happen with even the slightest cling.I don’t know if other customers have experienced this, but so far it has happened to 4 of my mugs. 1 or 2 I can see, but 4?? I don’t know. My other mugs I have in the house go through much more vigorous usage and the handles are all intact. That’s my experience anyway.
