Fits my bike perfectly, great tool!

Good tool to have in your kit.
The usual excellent Park Tool quality. This is one to have in your tool kit, as it works with 80% of the freehubs you're likely to encounter. You pay a little more for Park tools, but if "Made in the USA" means anything to you, and you want your tools to last, it's worth the extra cost. Well packaged

Well built and works perfectly
This worked perfect for removing the rear cassette from my bike. I did not get the tool that wraps around the cassette but I was still able to remove the cassette using a technique I found on the web (e.g. "what to do if you our out in the field and need to replace it".). Park tool seems to make some of the best tools for bikes and is a good value based on the quality of the product.

Wrong item sent.
I received an FR-5.2GT - a cassette lockring with a guide - rather than the FR-5.2 which is advertised. This tool is useless for unscrewing suspension fork top caps. Not worth my time or money to return it for a refund. Very annoying.
