i'm quite sceptical about the 'quality' of them. There were faily cheap, yet rated to at least 17,000NM . However when i recieved them, the bearings look like they're bronze, and the bushes look like they're nylon lined. (the actualy body is aluminium aswell.)
They can't be any worse than the ones i took off, so i might see how long they last. If im happy with them, ill either throw on some boots, or replace the rose joints with some higher quality ones.
As ive said before, ive got standard shocks, the springs are ment to be 40mm lower (they seem quite soft) so it does have alot of body roll, so its hard to feel the difference between the drop links.
