Gamerfinger optical PCB with sq gate + Spring tension. General opinions?

Heyo! Just ordered an optical to replace my aging JLF and appease my gf that is deeply annoyed by the clicks but I had a few questions for the people in the know:

  • will it work efficiently with a square gate?
  • doesn’t have a 2lb spring in stock. Will the copper thing be enough tension for a while? I think I have a few other Seimitsu springs too and 2 JLFs spring stacked in mine at the moment.

Any opinion on the performance of the thing? Is it the new Flash1 copy/rebadged? @jmanDMC maybe?
