Love the tumblers. They keep my cold drinks cold. I'm always getting comments about them, especially the claymore cup. Have not had these long but I believe they will last a long time.
Bought two of these tumblers previously for my son and myself and bought two more for backups to be sure we'd have enough cold or warm drinks available when on fire calls with our company. We also use them for our other activities. They're great for hot soups also. They keep their contents at temperature longer than any similar items.
Great cup to use around the office.
Got it for my father-in-law a vietnam veteran. He loved it.
What a great conversation starter, and it works really well, fits in a standard cup holder, keeps everyting hot or cold, what more could you want?
