Quoted from HaggisPinball:

Thanks to Cary for posting the review
I clarified a couple of points on the YouTube clip, so thought I would add them here as well:
Hi Cary - thanks for making the video - much appreciated
Just to clarify a couple of points:
1. Acrylic layer is 4.5mm (so a little under a 1/4 inch)
2. The plywood layer is 9mm, so I end up at a standard thickness playfield so standard mechs still fit
2. The test rig at the time I filmed that was at 504,000 passes (with a small double tap at the end of one pass, so that section probably double that) - it's now currently over 800,000 and there is no wear. That mark you can see is actually a dust line and cleans off with some IPA - I probably should have cleaned it first but I did literally take it off while filming. Interestingly, the ball spends the majority of it's time rolling up and down the middle, the vibrations sometimes shim it to one side, which of course it decided to do when I filmed it
Cheers,
Damian

Quoted from CrazyLevi:

I don’t know man a video of some hairy dudes love-tapping a thick acrylic block with tools and everybody thinks it’s a “paradigm shift?”
We’ll see. I’ll be pretty surprised if this ever becomes the “industry standard” but I’ll enjoy watching this play out.

Quoted from Yelobird:

Agreed and if the picture is a representation I will stick with pooling personally.
