One menstrual cup will last you forever.*. According to Diva Cupâs website, you should replace your cup annually. *Many other eco sites actually claim that with proper care, one cup could last 10 years.
When I was at Hartzell this spring (Piqua, OH) they mentioned that same range and I think they wanted it every 2000 hours or six years (I think). Yes Hartzell recommends 6 years BUT here in Canada, COPA has lobbied the gov't to allow up to ten years (with inspections) then mandatory overhaul. The shop I spoke to said, they still recommend what the manufacturer recommends, 6 years. Props that go the full 10 years are more often beyond corrosion/erosion limits.
