In order to keep the price down, I buy large bags of dog food for my small dog. Because of that, I need a storage unit that will keep it fresh. This unit, while not absolutely air tight, does a fine job on that score. The snap shut mechanism on the lid is easy to open, filling is a breeze, and so is scooping out refills for her bowl. The clear plastic body makes it easy to see how much food is left. Quality is top notch and it is attractive enough to be left out in the kitchen...no need to hide it away. This was a very useful and worthwhile purchase. No disappointments!
