Mine is the standard Magnum, about 6 inches tall. The housing is heavy
plastic; I expect it to last quite a long time.

As someone else said, a twist of the knurled nut on the bottom changes
the grind.

The only drawback is that you can't see the peppercorns. My previous
grinder was clear acrylic; it was nice to see multicolored pepper. Now
I just use black corns.
