Great tool. When you use this tool to adjust the valves on a 4 cylinder Honda engine, you no longer have to resort to screwdrivers and ring spanners. Honda V6 rear valve block near a fire wall is like torture without this type of tool. If you want to avoid torture and save time and effort, get a good valve timing tool.
Insert medium screwdriver. I realize this is new, but I'm forced to change this to make it work properly. I struggle with the tool when adjusting the valves, making the task more difficult than it needs to be. Otherwise the instrument appears to be made of good materials (just poor fit and finish).
The package arrived quickly but it was the wrong tool. Looked exactly like the picture and was packed with the right items but the wrong size. I ordered a 10mm lock nut tool and received a 12mm lock nut tool in a 10mm pack. I am very upset that I lost so much money on this job because I couldn't finish the job I started with the right tool. And now I'm stuck with this tool I didn't use.
