Query: Break too easily

Hi,Really like drinking wine from these glasses. Ended up with 8 each in two sizes. Broke my 4th glass the other day while cleaning it. NEVER broke any other end-high stemware doing that. Believe me, I've been very careful too.Also had one break in a very modern dishwasher operating on a crystal cycle.Just too thin and fragile despite the resonable price and good functionality
