I've just bought & fitted a pyramid one -
DONT BOTHER BUYING ITIt is held on with one tie wrap round the swingarm brace

. It rattles a little, but the extra thin layer of rubberised foam I added has help reduce any vibration.
It does keep a fair bit of crud off of the shock though.
I modified mine, seeing as it was so rubbish - now it has a drop down flap that stops crud hitting the rear suspension linkage - that bit works a treat

Just my tuppence worth.
