3D Printer Nozzles, 11PCS Hardened Steel MK8 Extruder Nozzles 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm with Storage Box Socket for CR-10/ Ender 3/5, Ender 3/ V2 Ender3 pro, Aquila

My brass nozzles had accumulated some debris from a glitter filament and were underextruding. Replaced with these and back in business. Be aware they are a little shorter than stock so you may need to recalibrate your z axis

Had success in the past with these nozzles. The second purchase also worked well. The only negative is the two sided installation. They do provide a wrench that helps removing and installing. Just don't misplace it.

I print mostly PETG, sometimes PLA on my mostly stock CR-10 S5 + BLTouch. Printer only came with .4mm brass nozzles. Heard going up to .6mm really helps with PETG, and I think they are right. I've only used one hardened steel .6 nozzle from this set so far, but really liking the results. I have had no clogs yet, even with first layer really pushed closely against into my magigoo + kapton print surface. I am seeing less stringing than with the stock .4mm brass by far. Not seeing under extrusions, in even .4mm layer heights. Pretty easy to get the detritus off the nozzle between prints too. Top layer surface isn't quite as smooth as with the .4mm, but that's probably to be expected with the greater size, vs a problem with these nozzles specifically.My only critique of these, and it's a minor one, is that the surface to grab onto with a wrench is only on 2 sides, not 6. Makes it just a bit harder to get the right angle for snugging the nozzle in. Again, minor gripe, but maybe they will change to the full hexagon in a future production run.

Comes with all the sizes you may need. Quality is good, doesn't clog easily.

I loved getting these nozzles since I have an Ender 3 Pro printer and have had quite a few issues with my nozzles jamming up in the past, the pack comes with hardened steel ones which will really help for if I choose to print more abrasive materials. The hardened steel nozzles aren’t hex, so you have to use their wrench, which is a pain, and the nozzle cleaning needle tube was in pieces when it arrived. Overall, not a bad set but needs some improvement in how their cleaning tools are packaged as well as some sort of labels on the bags to denote which nozzle is which for easy reference.

These nozzles seem to be fine and I can't complain so far about the print quality. However, the part where you grip them are rounded and only flat on two of the hex edges, so they don't fit into a hex socket wrench. This makes changing them a bit of a pain. Nice and cheap though.

I generally get 250 to 450 hours print time on a brass nozzle...... I upgraded to this about 2,000 hours ago. I've ran glow in the dark, color changing, ABS, ASA, TPU and the prints still look good..... This package is more than you're ever going to need your printer's going to break way before you go through these

You can't use your socket driver because it is not HEX, it is round with 2 sides flattened that why you need the stupid short included wrench. This is annoying when it comes to installation because you need to heat everything up before you install, using a hex driver is easy and safe, using the included wrench with this kit is difficult and you need to be careful not to burn yourself. The 0.2mm tip and 3mm tip keep getting clogged, but that maybe my fault in Cura settings or it isn't up to spec, who knows, I don't have a way to tell. The 4-8mm nozzles worked fine. Offsets are the same/similar to standard brass nozzles.
