I do not know what the other people who write reviews here, the Shaker have used, but as an extra dedicated cocktail man wanted to use, the glass was stuck after 2 seconds in the shaker. He then made the trip and a true Boston Shaker brought, with which he then served for 4 hours. Cocktails at my wedding and it's not become a flop.
PS :: this is not really a Boston Shaker, but a lounge Shaker.
