1piece Hardened Steel Nozzle V6 Nozzle 0.25/0.4/0.5/0.6mm for 1.75mm V6 Hotend Prusa Printing PEI PEEK or Carbon Fiber Filament use (1x 0.6mm)

Follow instructions on youtube and got the printer back up and working in no time, print quality and great and its been running like a champ!

Extrudes out very accurately. No problems.

This thing almost never wears out while using conventional filaments that aren’t abrasive. However, the price tag is somewhat high considering you only get one nozzle.

I wanted a hardened nozzle for using abrasive filaments. Also went up in size for faster stronger prints and probably less likely to clog.Easily the best upgrade to my printer. Now I can print any material and it takes less time. The 0.2mm increase in the smallest detail I have not missed at all, I increased my layer height a little and wait a little less. It was easy to install so if there is something I wanted to make in the finest detail I can spend a minute switching back. But even without arachne mode prints still look good. And the thicker perimeter improves strength. Also by allowing thicker layers prototyping is way faster, no turning back for me.

gives decent enough prints.

Advertised and marked as .5 mm, but it is a .4 mm. Caused major problems, and hours of time and money. I measured the tip compared to other .4 mm tip.

These are great! they print REALLY well, and stand up to Carbon Fiber nicely! I have put about 6 rolls of Carbon through one, and the walls measure the same, and it prints like butter!

the nozzle looks good but there's no markings to say what size it is. For that reason alone, it gets 2 stars in my book. Would have returned it if I had caught it in the return window. At least it's cheap.
