Review on Premium Cocktail Mixing Glass Set by Kevin Harmon

I really wanted this set to work because I love the style of the mixing glass. However, the mixing glass cracked the first time I used it. The glass was at room temperature. I added 3 ounces of tempered alcohol, then ice. About halfway through mixing the drink, the mixing glass broke on the bottom, sides, and all the way to the top. I suspect this is due to the temperature change caused by stirring the ice cream. The problem is that the glass wasn't warm before the ice was added, and a cocktail mixing glass obviously needs to be strong enough to withstand temperature changes. Unfortunately it wasn't worth the time to wrap it up to send it back for a refund. You might get a version that doesn't break when you buy it, but I wouldn't risk it.
