Didn’t work for my p1s
Style: P1 Series Hotend Hardened Steel 0.4mm
My printer has constantly had issues with this nozzle, i swapped back to my old one and it’s back to normal. I think this one had a defect, it would frequently split the filament when printing and create a mess.

Works great, but noticeably lower build quality than OEM
Style: P1 Series Hotend Hardened Steel 0.4mm
I ordered this for use on my P1S. It installs as any normal complete hotend kit. However, just examining it in your hands you can see that it is inferior to Bambu build quality. Further, after initial install, it gave hot-end temp errors that only cleared after unplugging and reseating the connector multiple times. That said, once that glitch cleared, it printed generally on par with my Bambu hotends. I don't print a lot, so long-term viability is less of an issue.

PLUGGED AFTER 20 MINS OF USE SAVE YOUR MONEY
Style: P1 Series Hotend Hardened Steel 0.4mm
Two different hot ends that plugged up beyond repair. You get what you pay for. Don't waste your time or money. They worked for 20 mins each then just plugged. Even tearing them apart was impossible to clean out and this was a just opened pack of pla.

A Seamless "Plug-and-Play" Lifesaver for the P1 Series
Style: P1 Series Hotend Hardened Steel 0.4mm
A Seamless "Plug-and-Play" Lifesaver for the P1 Series Rating: ⭐⭐⭐⭐⭐ (5/5) Headline: Saved my print job! Perfect fit, easy install, and handles abrasive filaments like a champ. After a nasty filament jam on my original assembly, I needed a replacement fast. I decided to go with this Hardened Steel 0.4mm Complete Hotend Kit for my Bambu Lab P1S, and I couldn’t be happier with the decision. 🛠️ Installation & Fit The "Complete Kit" aspect is the biggest selling point here. Because it comes with the cooling fan, thermistor, and heating block already assembled, you don't have to mess around with tiny screws or fragile wires while trying to seat a thermal sensor. Plug-and-Play: It fit right into the toolhead housing perfectly. Connectors: The plugs matched the board exactly—no forcing or crimping required. Time: I was back up and running in under 10 minutes. 💨 Performance & Print Quality Since swapping to this hardened steel nozzle, I’ve noticed zero degradation in print quality. Consistency: The heat creep is non-existent thanks to the included fan, and the thermistor readings are rock steady compared to my old, worn-out unit. Durability: Unlike the standard stainless steel nozzles, this hardened version allows me to run Carbon Fiber (CF) and Glow-in-the-Dark filaments without worrying about the nozzle orifice wearing out and ruining my tolerances. Flow: Even at the high speeds the P1P/P1S are known for, the extrusion remains smooth and consistent. ✅ Pros Fully Assembled: Saves you the headache of building the hotend from scratch. Hardened Steel: A necessary upgrade if you want to print anything beyond basic PLA/PETG. Direct Replacement: Indistinguishable from the OEM part in terms of fitment. ❌ Cons None so far—it solved my jam and has been running 24/7 since. Final Verdict: If you’ve experienced a catastrophic jam or just want to upgrade your P1P/P1S to handle more abrasive materials, this is the kit to get. It’s worth the few extra dollars to get the full assembly rather than just the nozzle—it saves time and ensures everything is seated correctly from the factory.

Quick and easy replacement of the entire hotend
Style: P1 Series Hotend Hardened Steel 0.4mm
This kit is a good idea for replacing what is probably the most critical component of a 3-D printer. The hotend is what heats the filament and allows it to be deposited accurately on the job. While the nozzle is what usually gets the most wear, other components on the hotend can fatigue and cause problems. This kit replaces the entire assembly, with a lot less fiddling. Installation is pretty quick and easy.
