Disclaimer: I didn't use it for its intended purpose so keep that in mind. I needed to remove a cam sprocket from a motorcycle crankshaft and this was the recommended tool for me. He did an excellent job with this task. At this price point it's clearly made in China but the quality and design seems excellent. It has a very large adjustment range. The block isn't square - it's wider on one side than the other, and all edges are slightly convex, giving even more room for customization. So the width at the top mainly depends on which block faces you attach the puller arms to. The thumbscrews for the underside of the arms might not even be needed - in my case they weren't, but they're nice to have.
