Query: All broken now

I bought a dozen of these glasses less than a year ago. The last one broke today. You have to treat these glasses like fine stemware. If they bang together in the sink, they crack and break. If they fall over in a sink full of dishwater, they break. I had started washing each one individually, but the last one finally broke.Perhaps, if you have a dishwasher they might hold up better, just don't over crowd them.I compared this manufacture's glasses to some that I've owned for years. The rim at the top of this glass was noticeably thinner than on my old ones. Perhaps I just got a bad batch, or they are really skimping on the amount of glass they are using to make these.The smaller, 14oz tumblers from this manufacturing have much thicker rims and I have not broken a single one.I can not recommend this product.
