Good but expensive
Works great on my P1S. Installation was easy. Price is a bit high though.

Overkill for standard PLA
Works fine but honestly the standard hotend is enough if you don't print abrasives.

Perfect for Carbon Fiber
Switched to this for CF printing. No wear after 500g. Quick swap is amazing.
