2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab | Removable Wear-Resistant Nozzle, Quick-Swap, High-Precision Leak-Proof, Heat-Resistant up to 350℃, with 2PCS Silicone Socks

The original clip that holds the nozzle on my A1 broke, so I bought this HzdaDeve assembly to replace the entire heating component. I’ve put 76 prints on it so far, and it’s working perfectly. The installation was straightforward and it feels just as high-quality as the factory part. The heating is consistent and I haven’t had any thermal runaway errors or issues with the nozzle seating. If you had a hardware failure on your hot end or just want a reliable spare to keep your machine running, this is a solid choice.

This product works flawlessly and I installed in less than 30 seconds

This is a direct replacement for the OEM part and performs flawlessly.

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.

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.

Overall assembly and installation of the product was simple. It fit well for my Bambu Lab A1. However, after using it for a week, the printer regularly pauses because of a temperature malfunction error. This was the problem that this kit was supposed to solve. Luckily the issue does not cause any major issues with printing, but it does require consistently checking the printer or the app to resume the print after it pauses due to the error. Though cheaper than an original one from Bambu Labs the inconsistency with the printing did not make it worth it. I will be buying an official one from Bambu Lab to replace this one and I'll keep this one as an emergency spare. Initial Review: 2 StarsUPDATE: The seller reached out and offered a full refund for my purchase, since this hot end failed to work with my Bambu A1 printer. For that reason I have updated the stars to reflect the seller standing by their product. Updated Review: 4 stars.

Works great

Not sure what the tools are for but its good so far.

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
