Beautiful, works well to keep hot beverages hot and cold drinks cold.
Negative Product Points
Fragile, expensive
Detailed Commentary
I purchased the whole range of sizes of the glasses, plus a pitcher and teapot. After one and a half years, most are broken despite careful handling. The smaller sizes, 2oz and 9 oz have stood up better, but almost all of the larger sizes, the pitcher and the teapot are gone. Some broke in the dishwasher without any impact whatsoever, a couple broke from dropping an ice cube in, some from an accidental tap against a plate or another glass. It's a beautiful product and works well at insulating, but they need to switch to a tougher glass formulation. I'm am never buying more, it's a waste of money.
Buying Experience
I bought the whole range and have experience with many pieces and sizes.
