I come from a family of do-it-yourselfers. Some of my brothers have similar items in their garages and have great success with them. When I decided to invest in tire changing equipment in my garage, I knew I needed one of these. Yet, my success rate on getting a tire back on the bead with this tool is hit and miss. Sometimes it takes five or six tries and sometimes that works and other times it doesn't. Using this tool does not require any expertise, as it is a simple process, yet not so great for me. Not sure what is different between this model and others I have seen used. It works, but not as efficiently as I hoped.
