32PCS Mk8 Nozzles 3D Printer Extruder Nozzles Hardened Steel, Stainless Steel, Brass High Temperature Pointed Wear Resistant Nozzle 0.4mm,Compatible with CR-10, Ender 3/ V2 Ender3 pro,Prusa i3

Havent used the steel nozzles, but the brass is working awesome! I test each new nozzle by pushing a cleaning rod through it so it was nice these came with them. Installed easily enough using the enclosed wrench and went right at an 18 hour print. Im impressed. Money (and not a lot of it) well spent.

This is a nicely-compiled set of nozzles and tools for a decent price. Nothing to dislike

These do the job well on my 3D printer. I have used the 0.2mm, 0.4mm, and 0.6mm nozzles successfully. They all appear to be good quality. Having a nice selection of nozzles on hand for different printing tasks as well as emergency replacement is essential, and these do the job nicely.

If you own a printer with a MK8 Hot End, this selection of nozzle is a good choice to have around as spares. Im not a big fan of hardened steel, but I like stainless steel and brass. This kit is a nice set for the price. Will worth a full 5 stars.

Not what I was expecting, hoped to match the nozzles included with direct extruder. The cleaning tools are nice. Decent for the price you pay.

Exactly what I needed!

No matter what 3d printer you have, you will eventually need to replace the extruders as they wear or you encounter an issue. This kit provides a decent variety of steel and brass replacements in several sizes, so that you can adjust your extruder to both the type of filament and size of filament desired...some filaments are more abrasive than others and sometimes a wider filament does a better job depending on what you are printing. The extruders are reasonable well finished, and the interiors (where it matters) were smooth on the kit I received. The threads were clean and swapping out the extruders did not come with the feeling of imminent cross threading, which would have required replacing the heads.

Nozzles constantly clogs or messes up prints. Slapped an old nozzle in problems stop. I dont know if its a bad batch, or they just bad in general. The tool that was included is nice.

Nozzles are showerer than expected for a Prusa MK2.5s and Prusa Mini. This means you will hit the heatblock without an gap which will cause you to have a filament leak. You will need to adjust your heatbreak down to close the gap but you may not be able to. These are usable but it would be better to get nozzles that are the right length.

Got what I asked for, my printer was acting crazy bubbling all my plastic figured it was a jammed nozzle put on one of these new ones and bam problem fixed.
