2 Pack A1 Mini/A1 Hotend Print Head Hot End Kit Extruder Upgrade High-Temperature 0.4MM Hardened Steel Nozzle Replacement with 4PCS Silicone Cover Sock for Bambu Lab 3D Printer Accessories

I used this hotend kit on a modded Elegoo Carbon Centauri and it worked perfectly. Everything fit well and installation was straightforward. One of my favorite features is the quick swap nozzles — it makes switching between different nozzle sizes fast and hassle-free. Having multiple sizes included (0.2, 0.4, 0.6) is a big plus. The hardened steel nozzles are a huge benefit. They give me the confidence to print abrasive and higher-temperature filaments without worrying about wear. Overall, a solid upgrade that performs exactly as expected.

The quality is very good, I bought these as spare items for my printer. I have since began using one and it works very well.

100% agree with other comments, bought from another brand that claimed to be an “upgrade” and couldn’t get it to clasp on the Hotend. Bought this one installed in minutes and first print was flawless! Highly recommend this since the Bambu one is always out of stock.

The hotend assembly doesn't secure my nozzle well. The clasp does not close easily like the original Bambu one did, and the top of the nozzle often gets slightly dislodged from the magnetic connection on one side. I've been able to successfully print some things with it on my A1 mini, which is why I gave it 2 instead of 1 stars. But from the moment I installed it, I started having nozzle temperature malfunction issues, which I never had prior to this assembly. I'll fix the issue, get a few more prints that turn out okay, and then the nozzle temp malfunction error crops up again. UPDATE: Lowered review to 1 star. After 3 months, I've still been having inconsistent issues. One of the small screws on the back of the assembly came loose and somehow fell completely out (despite the three main screws being firmly in place). I undid the three main screws, and two of the other small screws on the back fell out before I'd gotten all three big screws loose. I was excited that perhaps I'd at least found the culprit and would only need to tighten the four screws in the back. I tightened them, screwed the three big ones back in, and tried to print something only to get a nozzle temp malfuction/open circuit error. So I unscrewed the big three screws and took a look at the back so see what had happened, and the white wires in the back had pulled free, rendering the entire assembly busted and my machine unusable until a replacement part can be ordered. I thought saving a few bucks by buying a non-OEM brand assembly with free Prime shipping would be a good deal, but i wish now I'd spend the extra $10 upfront. This "deal" cost me more than that in wasted filament and time.

Works amazing!!!! I was so worried it wouldn't be a good fit for my bambu A1 mini, but it was super easy to install and thankfully cleared up the issue I had with The blob of death!

Something wrong with the temps on these. Whole house smells of burnt plastic after using this and have had multiple failed prints due to clogged nozzles. After giving these another shot, they actually work pretty well. Some kind of nasty off gassing at first and I found that turning my temps down a hair really seemed to work well. After using for a while now, I'm changing my rating to 4 star. Their CS reached out to me to provide a refund for the product as well but at this point I really don't think that's necessary. I would buy the .4 nozzles again.

These worked great one my bambu a1 mini printer!

So I recently bought a third party hot end assembly from another seller because they could get it to me faster, but it didn't clasp right. This made me a bit skeptical about ordering another hot end assembly that wasn't OEM. However, vi am very happy to report the one from this seller works great. My printer was having really bad issues and now it's working like the day I got it. Installation was straight forward and the print quality is literally perfect. I'm not sure the original worked this will. I might dock half a star because the clasp is a little imperfect, but so was original OEM one and it's really not a huge deal. Basically, it did what I was hoping it would do and at half the price. For that, five stars. I am not associated in anyway with the seller and did not get provided anything or have anything to gain. This is a 100% unbiased review. If you're looking for a new hot end assembly, I recommend this seller.

Absolute Waste of money, after 2-3 hours of printing both my printer has clogged extremely and had to change the Hotend Heating Assembly to fix the printer costed around 5-6k
