I've got two of these and they're awesome,
My Classic keeps ice for about 4-5 days, the Signature keeps ice around two weeks, fetching a few beers every second day.
For the dollars, I think they're the best:
Esky
Ice Box
Cooler Chest
Cooler Bag
Ice Bin
Chully Bun Bro
If you only have a typical esky from the hardware store, give it to the homeless shelter and buy one of these, they're so good for going camping on the piss and deciding to stay a second night because your friends aren't man enough to help you drink all the beer.
how does this compare to their ebay pricing?
