Just a quick testamonial to how well they keep things cold.
I used mine last weekend and forgot to empty it when I got home...fast forward to Wednesday and as I was putting my lawn mower away I spotted it on the bike and I decided I better empty it.
Mmmmm the beer was still cold, with a little bit of ice still remaining.
And oh by the way it has been close to 100 the fast two days and probably even warmer in my garage!!!
