I'm having trouble understanding the question too.
Is it just that you keep having sensors fail?
Don't know what to say. I still use my GSC-10 with my Garmin Edge 530. It was given to me by a bike shop owner/mechanic circa 2016 after hearing the story of my water bottle falling out of it's cage and knocking my previous GSC-10 off the bike and losing the battery cover. It came out of his junk bin so no telling how old it is.
I haven't had any issues. Though I'm starting to wish it would fail so I can justify getting the new style Garmin speed sensor. Cadence comes from the PM now so I'm not using that side of the GSC-10.
