Refrigerator spills

I was getting tired of items in my refrigerator rattling around and falling out when I travelled and opened the door on arrival even with the spring bars. Then I met a guy at a campground who told me about a product he used called "Shelf Hog". He showed me this neat little thing that inflated to fill the empty spaces and lock things in place. He said he used them everywhere like his medicine cabinet and overhead bins too. I googled it and found their web site. I have been using them ever since. Nice thing is you can let the air out and they stow away in a drawer. Such a simple solution to my age old problem and not expensive or complicated to use . Like WOW!
