My daughter was so shocked when she came over and picked up one of these glasses because they look so much like real glass. The glasses are lightweight and durable. They look awesome. I have been washing them on the top shelf of the dishwasher and they come out fine. I do dry the glasses when they come out of the dishwasher, just as I would real glass so they don't spot. Our cat knocked one of the glasses off an end table already and it did not break. I am considering buying another set already just in case they stop making them. I love these glasses!
