I wanted to take a chance but was disappointed. The tool's threads felt like they were drying out with use and after I lubricated the threads it ran smoother, but looking closely I saw that the measuring faces met at an angle and didn't match that this is due to poor workmanship. More of a toy than anything else, this tool can at best be used as a teaching tool to teach you how to read a clock face. Not worth sending it back for the price, just want to say this is by no means an accurate tool.
