    Words alone cannot express how thrilled I am to find this tool. I have been battling round downspouts for over 20 years trying to make them look as good as possible. I never knew the expander existed until I discovered the Stortz website by accident. The tool replaces all of the frustrating effort to make round downspouts look their best. I absolutely love this tool. It is definitely one of the greatest discovery I’ve ever made professionally. Thank you Stortz.

    Tool is heavier than previous models, prohibiting use of cordless drill. Works as expected with corded drill.
