One-line verdict

For ultra-compact espresso and pour-over users who need a tiny scale that still delivers Acaia speed and build quality, it fits tighter spaces than the Lunar while adding Bluetooth the DiFluid R2 lacks, though the platform is smaller.

How it compares

vs Acaia Lunar ($249): Acaia Pyxis wins on compactness and lower price, Lunar wins on larger platform and waterproofing
vs DiFluid R2 ($105): Acaia Pyxis wins on premium build and app integration, DiFluid wins on faster espresso-specific response
