What do people mean when they say the old Grind Machine or the new Grind Machine ??? ?
There is an older version of the grind machine and a newer version and also a metal version.
I know for a fact that the v2 is much better than the original evan though it was only tweaked slightly.
Scroll up to yyf and click on gm and read the paragraph.

Thanks. What did they “tweak”?
Again, thanks
They PGM V.2 has weight rings, and a different decal. And yomac 888, please try not to post multiple times in a row.
The old PGM Had weight rings too. The Texture on the out side it different and colors.
the weight rings were already mentioned.
are the GM2’s (metal) discontinued?
Yes.
Other way around.
V.1 Had weight rings, V.2 did not.
umm i have a pgm v2…it has weight rings.
v1 had four rubber weight rings. v2 has molded plastic weight added. Looks like weight rings.
Also you guy’s are missing something. the original GM was a metal yoyo that didn’t have the H shape.
If you are referring to the plastic version then it’s the "P"GM.
