Amal will have actual figures, I can only comment on what I see here on the forum.
I would say your installer is technically correct.
HOWEVER,
“More prone” still doesn’t mean many nor frequent.
The failures I have seen have been from experimental implants, or placement in areas they shouldn’t be (knife edge / P5).
Some faliures were due to the installer not making a cavity large enough and bending when forcing it in.
There was an issue with some chips on the new style pcb flex boards, but that has been remedied.
Here’s some more info on how robust Flexies are.
I have a number of Flexies still in me., I have removed one (expired custom payment implant) and I moved positions of another.
Zero failures.
I currently have a Vivokey Apex Flex in P1 and I have had that since it was first released.
