How long do budget hard coolers actually keep ice?

Manufacturer claims for these models range from about 2 days (Coleman Snap N Go) to 5 days (Coleman Classic and Xtreme), but those figures assume pre-chilling, a full ice load, and limited lid opening. Real-world retention in hot weather is typically shorter. Because the data supplied for this roundup contained no independent ice-retention lab tests for these listings, treat the day counts as marketing claims rather than verified results.
