Title: Poor workmanship
Review: This puller accomplished the task (pulling a crankshaft pulley). It is a poor quality tool though. It is certainly not designed to last a lifetime. The treads do not run smooth, and the metal feels weak. I would not have been surprised if it would have stripped the threads on the first run.
