I bought the personal model 26qt. It holds ice for at least 3 days I always chill my drinks in the fridge so the ice don't melt coming in contact with a hot beverage!I know I walk all over it with 265lbs. and it don't flinch.The rubber legs makes it stick to a surface.Does not slide. And Rees, you need a winch to get that size cooler in and out of something. The cooler empty is pretty dang heavy.They claim pank has a calming effect on the brain!They painted holding cells pank and the arrestees seemed to calm down faster than with any color.
