High flow performance
Noticed better layer adhesion at higher speeds. The hardened steel handles the heat well.

Works well but expensive
Does the job perfectly, just wish it was a bit more affordable for hobbyists. Otherwise no complaints.

Good upgrade, slight learning curve
Quality is excellent. Had to recalibrate flow rate after installation but prints are much smoother now.

Durable and reliable
Been using this for 3 months with glass filled PETG. No signs of wear on the nozzle tip yet.
