Much the same tbh; still continuing to impress with no sign of getting close to wearing out yet; although admittedly I've not been out on the bike anywhere near as much as I'd have liked during the past year.
FWIW the highest mileage chain continues to be the one that's the subject of this thread, which is now on a little over 3k miles and still shrugging off any attempts from the chain-wear checker to write it off
I did buy a couple more chains as they were a good price at the time, however waxed them as soon as they arrived and probably missed a trick as one would have served as a decent side-by-side comparison for wear / elongation with the original.
As you can tell from this thread I'm a big fan of waxing; best thing I can suggest is to give it a go and see how you get on
