Works well. It compresses wonderfully. It was difficult to say what will be in the package so I wanted to post more information here. I received 8 3 inch pieces of adhesive backed shrink wrap of various sizes. The packaging says it works with 20 to 2/0 caliber. My package included: Qt 1 3/4" Qt 1 1/2" Qt 1 3/8" Qt 3 1/4" Qt 2 3/16"
