I purchased three Rubbermaid 5 gallon water coolers for use with our running group. We use them every weekend and haul them all over the place filled with water and/or sports drink. My only complaint is the lids will leak even if they are screwed down correctly and tight if they fall over. If you don't put the lids on right, they will also leak while hauling them about as the liquid splashes inside the container. The lids sometimes take a time or two to screw on correctly as the threads don't always line up correctly the first time. Insulation is ok, about what you'd expect from a cooler like this. All in all, very pleased with the product as it has held up well over the last year of being hauled all over the place. One last thought, make sure you unscrew the lid slightly when you're ready to use as it will sometimes create a vacuum which will keep the spigot from flowing.
