@daveyf , I'm using the Onzow for more than 10 years on my cartridges (Ortofon Kontrapunkt Blue first and Cadenza Bronze recently) with no issues. I guess that most of the problems arise from user mistake. I've also used for many years the Last Formula 4 without any damage to the cartridge (Shinon Saphic, Kiseki Purpleheart, Carnegie One, etc..).
I've seen diamonds gone from the stylus on several cartridges, last week a customer brought in a Grado Reference Platinum, s**t can happen!
