Perhaps the larger model works well. This smaller magnetic set is tragic. The only upside is that if you're working on your grip strength, these will probably help. To get a useable amount of pepper, you'll have to squeeze 15-20 times. They feel cheap and destined for a quick trip to the trash can. Stick with a tried and true twist grinder.
