Just found out those cheap door restrictor switches are failing on newer installs

I had a job last month in a 6 story building where three cars kept getting random shutdowns. After chasing ghost faults for two days I found the magnetic switches were getting weak after only 8 months. Anyone else seeing these Chinese knockoffs fail way earlier than the old ones?

Global standard magnetic switches are fine, the issue is installers buying the cheapest garbage on Amazon.
