I got the pepper grinder — we go through a lot of pepper.
If anything, the pepper maybe does not seem as peppery as some other, including supermarket, brands. On the other side, make it up with volume. But I did buy a second Costco pepper grinder. The first grinds out of the second one definitely were pepperier than the end of the first.
As noted, it takes a long time to use up that much pepper. For the few bucks difference, and the long time the Costco peppercorns sit, I think I go back to the small bottles of McCormicks from the supermarket. After I finish the second Costco grinder.
