Hey fellows i need your opinions. I need to get myself a grinder because breaking it up with my hands has gotten old. Okay, i have 2 in mind. Mendo Mulcher 2.25" Or SPACE CASE Titanium Grinder Sifter Magnetic 4 P I'm kind of leaning towards the Space Case because of the friction nylon ring, i think it would make a noticeable difference in effort and noise. Thoughts? Does the nylon ring help?
