What do I need to know about this design
All you need to know about its "design" is that most likely you will destroy the cantilever accidentally before you stylus wears off. This mistake will cost a lot. Just look at this cartridge.
It looks like it was made to destroy it, really. Same with some VdH and Lyra cartridges.
Practically it is so inconvenient, you have to be extremely careful each time you unlock your tonearm.
On better cartridges a cantilever located under the cartridge body, not 100% safe too, but much better for safety reason.
