It works, cheaper versions don't.,

This review is from: Park Tool FR2C 2-Pin Bicycle Cassette/Freewheel Remover - Black (Sports)
Tried a cheaper tool which had a big hole through the centre making ITT diifiucult to fix to freewheel with QR skewer, and the pins bent before the freewheel on an old 70s bike moved.
This one fixed in plasce with the QR skewer really well and stood up to some serious hammering to loosen the freewheel. Which eventually loosened. Great quality!
