Neat guide, mr mojo. I just sort of stumbled upon this and figured since I own both a sharpstone grinder & dowel press, I'd read through your guide.

I bought their mid sized grinder with a clear top (off eBay - probably last year). It's seen heavy use no doubt. Long story short, isn't a knockoff.

Now, I did buy a sharpstone pollen press (not the T) off an unauthorized seller. Successfully pressed some kiefer sutherland w/ great shape, but there is space surrounding the dowels, not as exaggerated as your comparison picture.

Needless to say, the grinder has experienced hardships, so I'm in the market for another, thought I'd maybe ask before shelling out $
