I bought this after I realized that my FR-1 tool would only work with my SRAM lockrings. I figured it was cheaper to buy a second tool and made more sense than replacing all my Shimano lockrings with SRAM models! It works like it's supposed to and the price was great. In fact, the design is better than the SRAM version because the splines are better defined, which results in no slippage.
I recently bought some Zip Firecrest 404's from Western Bike Works and needed to change the cassette from my old wheelset to the new 404's. Using the Park Tool FR-5 cassette tool along with a Park chain whip I was easily and quickly able to change the cassette over to my new wheels. By the way - love my 404's!
