"Really easy to fit (although I do have some spare bits!) with a nice solid feel to changing - there's a ratchet somewhere in the mechanics which give you a tiny tic noise/feel as you change which when on the move is great!
Best of all - suddenly I have a full range of gears again! :)
The only negative (and it's a small one) is a lack of instructions, but we're not talking about astro-physics here - it's easy enough to work out!"
