I've had mine on for coming up a year.
The rear shocks had some surface rust on them so I rubbed them down and painted them in wrinkle black last week, the fonts are in good condition still and I can adjust them (with the crap spanner) whenever and easy as they havnt rusted up.
Quality and feel of the materials used I always thought was abit yucky, they do lack quality there is no doubting that but they are more than adequate.
Ride wise, when I was low low they where bouncy due to loosing spring preload, it was low and slow.
The car is still quite low but its a much more realistic driving height and it rides really nice. A firm lowered feel and it handles well when you poke it with a stick or "fist it". I wish I did have 700 quid to spend on coilovers but for 163quid I'm more than happy with these,they have caused me no problems.
