Anyone tried Herbie's mat on a Rega planar ?

My main problem with the felt mat is that the records can slip, especially if the center hole is a bit worn. The herbies mat sounds like it might eliminate slippage.
Does anyone have direct experience with this particular mat ?
There have been several posts about Herbie's mat on Vinyl Asylum in just the last day or two, including a full review by one inmate. Worth checking out if you havn't already seen them.
I had one on a P3, worked wonders, lowered the noise floor, increased my bass response and all for under $50!
