Just in case you thought you had the bad apple. I can report a similar experience with the same chain. I got barely 1000km out of the first and less than 2000km out of the second, before they stretched too far for my chain checker. (I did ride through a lot of bad weather with the first chain). My cassette survived due to keeping an eye on the chain wear.

I suspect when they talk about the ability to withstand abuse, they really mean neglect. For many bikes rust prevention would be a higher priority than wear.

Wish I'd seen these reviews before plonking down the cash on two of these from Wiggle... :(

First ride out, I found that this chain was pretty rough compared to the Shimano HG40 it replaced, even on a brand new cassette. It skips, it's noisy and I've taken it off after only a few hundred km. I tried my hardest to tune it properly, but I could never tune the skipping out of it.

Agree with the above. Don't buy.

Edit: Just noticed that the OP was about the Z8. My post is in reference to the X8 Anti Rust. KMC chains used to be very good. This is a little disappointing.
