This has been working really well in combination with the Panda Extruder to help reduce clogging, and overhang performance seems to be okay (not a crazy difference for the prints I've done so far, but perhaps marginally better than stock).
**Be sure to check that the air ducts are clear before installing!** Based on other reviews I'd seen online about this, I made sure to really clean out the air ducts before installing. A combination of tapping the sides of the air ducts at the bottom on a desk and blowing compressed air through them resulted in dislodging chunks of powder that were stuck in the ducts from the printing process of the part. Hopefully this is something that can be improved in future manufacturing runs to ensure that the ducts are nice and clear before reaching the end user.
