Odd question, but does the Magene PES crankset/spider work with any different brand left crank arms? Would a Senicx PR3 left crank arm work?

I've been using the sidebike 028 for a few months and really like them. Fits like most chinese brands so as long as you don't have overly wide feed they should work.

So, is this something that Magene is going to fix?  I'll be in the market for one of these types of power meters, so I'm trying to decide between Geoid, Magene, etc.

They ended up agreeing to replace it under warranty relatively quickly which is a good sign.  I also got it quieter (for now) by cleaning and greasing the crank/spider interface not the lockring itself.

I got the same creaking/clicking issues others have had after a few thousand kms and cleaning/regreasing only buys me an hour or two of silence before it comes back. Luckily Magene is already sending me a replacement of the entire power meter minus the left crank arm under warranty.
Also from my messaging of them, it sounds like Magene thinks the source of the noise is the interface between the crank arm and the spider, not the lockring which others have suggested.
