I've owned the HFN&RR test record for about ten years. It hasn't left its sleeve in the last five and I've set up dozens of cartridges on multiple arms without it.
If I connected a cartridge with the channels reversed or out of phase (did that once, lol), I'd surely notice the moment I spin a familiar LP.
I find it useless for anti-skating, which I can adjust more accurately and faster by listening to music.
It does work for fine-tuning azimuth, provided that you have a Fozgometer or a bandpass filter + multimeter/oscilloscope and the time to fuss with them. I've done it. What it taught me is that I can fine tune azimuth as accurately by listening to music, and faster too.
Stringreen's right that you need one to use a Fozgometer. Of course that just brings us to, do you need a Fozgometer? ;-)
