Query: How did I can before I bought this?

This has to be one of the most useful kitchen tools I own. No more trying to separate my lids in the pot of hot water with tongs. Makes canning go faster and anything that gets me out of the kitchen quicker is great. Works exactly as advertised- easy to use and cheap. If you don't have one and you can you are missing out.
