Very good for the cost. I am a bit prone to breaking them, but the bright idea I had to get fully thick glasses so they wouldn't break didn't go very well. The wine glass is very important, and of course, anyone who doesn't know won't understand exactly what changes. Better to break one or two but at least enjoy myself when I drink wine. Of course, there are much, much better and more expensive ones. This particular glass is excellent value for money. These ones have a good shape for white (and rosé).
