It's "Mazzer" (there is no letter "S" in the name of this grinder).
The Mazzer grinders are very easy to clean. If you want into the burr area you just remove the limiting screw from the collar (I have mine permanently removed) and then you can unscrew and remove the upper carrier. Clean inside with a vacuum and toothbrush and reassemble.
Mazzer keeps closer tolerances on the thread engagement so there is less backlash. This translates into a more precise adjustment with NO NEED to tape the burr carrier threads. At the very most, perhaps a light dab of foodsafe grease to lubricate the threads (be careful not to trap coffee dust on threads with the grease, it will make the assembly get "gummy")
Rocky grinders often benefit from a layer of teflon tape, and this tape would complicate matters for someone who wants to frequently remove the upper burr assembly to clean inside the burr area.
I would personally choose a Super Jolly over the Mazzer Mini, they are frequently available used for less than a new Mini. Of course with a used grinder you will probably need to do a deep clean, but that shouldn't pose a problem for you
