Whoever designed this at Rubbermaid needs to be promoted or at least rewarded.  The design is a perfect solution to tight space behind the seat of your car or truck.  Why?  A. It is simple.  B. Rubbermaid resisted the urge (I'm guessing here) to install a drain plug.  A drain plug would only be one more thing to break.  This cooler is light enough and ergonomic enough to enable one to pick it up and pour out the water while holding back the ice with their hand.  C. It is essentially, an insulated rectangular bucket with a lid.  D.  Oh and by the way..the lids are well designed too.  Why?  Well, there are two lids, side by side.  So one can be opened by the person in the beach chair or passenger car seat without needing to open the entire lid to reach for a beverage or baby's milk.  E. The keeper is a good design as well because it can be used to secure the lids in place.  Then, after use I use the keeper to hold open the two lids to dry out the cooler.  It insulates well.  I have been surprised of the need to dump ice after a two day trip in the mountains.  This cooler is never out of my Toyota Tacoma Access Cab.
