These are great "guest glasses" for clumsy company, but not much else. They don't hold a chill well, and feel too fragile for freezing. Won't even chance it. They're just a tad too shallow for standard cocktail measurements, so I've had to redo my "built-in" recipes. Not the end of the world, but kinda annoying at first. The shape is a little awkward for the larger-nosed among us. Still, they have yet to break and hold liquid without tipping over. As such, hey, they work....but are far from an ideal cocktail glass.
