Despite over 29 years as a cyclist I had never owned a cassette block. However, this more than met my expectations. 8 sprockets are more than enough for me and mounting to the wheel was straightforward. Lockring goes on fairly easily, and is so much easier to remove than unscrewing a threaded block with removal tool and bench-mounted vice; not to mention determination and musclepower ! To mount the freewheel you do not need any tools at all as you can tighten it by hand, HOWEVER, you may still need to remove the previous one and this could require a chain whip...it all depends.
On the bike what impressed me was the smoothness of the changes - no rattling only a very gentle whirring sound. The computer designed tooth profile is clearly extremely effective. Shimano have been producing quality components for many years and I have never had to complain about their products, and so much less expensive than Campagnolo.
I made sure to buy sufficient range to tackle steep hills in the district, and 11-32 teeth is perfect in all regards. This produces a low gear of approximately 25", and a high of over 100" which is more than adequate, unless your name is Bradley Wiggins.
