I waited to review until I had washed and used these glasses a couple of weeks. Right after I bought them I went back and bought two more sets. They go in the dishwasher and I've had no issues with them at all. No marking, no scratching, no cracking, like some do. I use them constantly with three college-age boys, I should call men now, but the constant soda, water, milk, etc, and there is always a load in the dishwasher and sink. As any Mom knows, they are under the bed, on the floor or left outside, so you look for things that take abuse. So far I have not found any better for the price and I recommend them to anyone who wants something that looks nice but can take a hard use daily.
