I bought one of these and for a week it keeps my stuff cold, I just drain a little water off and then add 20 pounds of Ice every three days. The problem that I have now is that the rubber casket is frayed and has broken where the metal lock area is. I now need to find a new rubber seal to fit it. I don't know why this has happened at this point on the cooler. I need to fix this or I will have to go buy a new cooler.
