Sorrento Plus 2-Piece Double Wall Glass Coffee Mug Set

I'm a big fan of the Zwilling brand and absolutely love the design and feel of these cups. They're made from high-quality, durable borosilicate glass and look fantastic. However, I've been disappointed by how easily they crack. I purchased my first set (a pair) three months ago, and one cup cracked not long after. I liked them so much that I bought another set, but unfortunately, one of those cracked too while I was washing it. I really appreciate the quality and aesthetic, but it's hard to justify replacing them so frequently.
