Overall this is a great bin. My husband and I debated whether we should use it store pellets or cat food. We decided on storing the cat food in the main bin. In the upper bin I store my cats treats and brush. I like that its on wheels and maneuvers easily. The lids are a bid flimsy but not a huge inconvenience. This product is perfect storing pet food or for anyone with a pellet stove looking to store pellets.
