Works exactly advertised. Glad I bought the dual sizes. And I’m glad the unit is made of steel. It takes a lot of pressure.

Wish I would have bought this sooner, sure beats using a clean shoestring or something similar to stop the piston, cleaner, and probably much safer for the chainsaws.

Better than the plastic ones

Whatever you do, don't buy the cheap plastic version of this tool also listed on Amazon. It will break on you. You gotta buy this high quality metal part to get the job done right.

This is a God send if you are working on small engines for feed eaters etc stops the piston moving so you can replace pull cords and carburetors. Cheap and saved me a lot of time.
