Works great, well worth the small investment
Bought this for my Creality K1, and it’s been a solid upgrade for my 3D printing projects. The kit, with its high-flow copper alloy nozzles (330W/m·k thermal conductivity) and durable hardened steel nozzles (7.8 Mohs hardness), handles everything from PLA to abrasive carbon fiber filaments with ease, supporting high-speed printing up to 600mm/s. Swapping nozzles is quick thanks to the K1’s design, and the nickel-plated copper nozzles ensure smooth extrusion with no clogging after 50+ hours of printing PETG and PLA-CF. The 0.6mm nozzle is my go-to for balancing detail and speed on functional parts, while the 0.8mm shines for larger models. My only issue, echoed in some Amazon reviews, is that the hardened steel nozzles struggled with PLA adhesion on my first layer until I tweaked bed leveling and temperature settings. The tin case is handy but tightly packed, making nozzle removal tricky without pliers. Overall, this kit’s versatility and quality make it a must-have for K1 users looking to expand their printing capabilities

Not the right fit for my assembly! (My fault)
They were exactly as advertised but, my printer is apparently a unicorn! 😂They didn’t fit in my printer but, it was my fault. The value was there and the quality seemed really good but, they wouldn’t work with my assembly.

K1
They work great with the k1 have so far only used the .4 nozzle but seems to be working great 👍

Do you have standard nozzles or a unicorn nozzle… Check first…
These nozzles are not supported by Creality’s printers as they are all upgraded to the unicorn nozzles… Disappointing but I do not blame the seller, the manufacturer does not explain this… I didn’t return as I intend on buying another hot end element that supports these nozzles…

Trouble getting first layer to stick with hardened nozzle
I got a clogged nozzle on my K1 and ordered these to replace it. When they finally arrived I figured I’d try a hardened nozzle since I had it, even though I was only printing PLA. Unfortunately the filament just wanted to curl up on the end of the nozzle and i couldn’t get a bit of filament to stick to the plate. I even tried a second hardened nozzle for kicks and had the same result. I had more failed prints in two hours than I’d had the entire time before I got these nozzles. I was about to contact Creality support thinking i had bigger issues but thought I’d try one of the regular chrome nozzles before giving up and wouldn’t you know, my printer was back to its old self! This is the first hardened nozzle I’ve ever had so maybe they can’t be used with PLA and I just didn’t know? At any rate, I has no luck with the hardened nozzles with pla or pla +.On a side not, the nozzles being in a tin is neat and all but it’s so small and they’re so tightly packed in foam I had to use pliers to remove them. IMO a plastic bag would’ve been fine and probably cheaper too. Not a big deal, just kind of annoying.If I need more nozzles down the road I’ll just pickup some of the cheaper, brass ones.

Great backup nozzles for the K1 printers
I sometimes print with glow in the dark filament which is abrasive. My Creality K1 printer did not come with any extra nozzles so I was happy to this pack of extra nozzles. Even if you don’t use abrasive filament nozzles will eventually wear out. This will set me up for a good amount of time.

Correct size for CR-M4 – volcano ones will work but not quite correct. selection of sizes and materials – i have tried different ones and settled on the hardened 0.4 – reliable and can just switch materials without much hassle
