I have had a set of 4 for years. Thats the only ones my husband wants to use. They are a little etched but it doesn't bother us. I have some of the similar ones from Walmart with the straw. They will break, the 2 sections come apart, if you drop them. The worst problem I have is he leaves them in the garage when he's working down there and forgets to bring them in the house. Yuk, moldy iced tea.
