I used the tool to check out my number one cylinders exhaust valve. The tool is aluminum alloy and is light weight but seems strong enough for the job. There was no bending of the tool in use. It works fine. Expensive for what it is.

The price everybody charges for this simple tool is beyond stupid high. They know you need it, and they make you pay to get it. No scruples, no shame. Nearly a hundred dollar bill for a bent piece of aluminum. And this is the cheap version. Sheesh!

This tool lasted for eight years with all kinds of student abuse at our A and P school. It took only one student not paying attention to break it. If it were made of steel a student could break it.
