Has anyone tried the $80 Bulldog Polisher for their balls?

I bought a knockoff on clearance at a rock store going out of business and used the walnut media and collinite metal wax.

It does improve the balls, but it is a slow process.

Just curious if anyone went with the Bulldog.

BTW, I called Flitz looking for their "Tumbler Additive" and they said it was the same as their normal stuff just a different label.
