Knocked the glass over on a stone counter top as it fell to the floor it hit the heat register. Not a scratch. An ordinary glass would have shattered.
I bought these for my wife as she is very fond of them. They are stylish and very durable, OK for the diswasher and at a very reasonable price...we have over a dozen of them and are our every day glasses as well as for informal entertaining. They are listed as chardonnay glasses, but we use them mostly for reds.
