I have it on the HRX. As Jameswei states it works very very well. On any LP's with any type of warp it flattens it perfectly so to allow your cartridge to work easily.
That said, there is a difference in sound with and without.
I have found that the sound with is a bit more controlled and probably a little less hash in the high frequencies.
Without the music has a little less contro, and a little more sparkle in the higher frequencies.
I alternate back and forth depending on my moods, but definately a worthwhile thing.
Even if you do not use it you can just leave it on the platter under the vinyl.
The new platter and bearing vs the old (at least going from TNT Hot Rod top HRX) seems to be that the new is more even handed, neutral and transparent
cheers SR
