My husband and  travel quite often.  Since he is diabetic we need to have a cooler to keep some of his insulin cold . When we traveled to  Florida several months ago, we were very disappointed  that the cooler we purchased .  Because the cooler advertised    as ice for 5 days, we were lucky if ice stayed frozen 2 days. We have purchased Coleman products for many years, so to say we were disappointed is being nice.  i guess we will have to get the medal cooler out of the attic.
