I've had mine for a few months now and they've survived plenty of hand washes without clouding or chipping. The stem feels sturdy enough for everyday use, but they still look nice enough to set out when friends come over.
The 18.25 oz bowl gives a full pour of cabernet plenty of room to breathe, and the stems feel solid in hand without being clunky. Eight glasses for the price of a couple of fancy singles means I'm not stressed when one gets knocked over on the patio.
