I purchased this tool when a friend asked if I could help him change a timing belt on his Honda Civic.  I had never done a timing belt on a Honda before, but after a little research a knew enough that I should pick up this tool.  To make a long story short, plans changed and I didn't change the timing belt, but now I have this tool.  I'm not complaining, because I love having specialty tools in my tool box, but I was sad I didn't get to try it out.
