You hear enough horror stories online you don't know what to trust. However, many of those with these hot ends are because the individual didn't install the nozzel correctly. I already have a 0.2 and 0.4 mm hot end and both work fine with the A1(I even had a malfunction where the filament jammed up and encased the entire Bambu Hot end. The these issues aren't limited to off brand parts.That being said, these seem to be well made off brand hot ends and the ability to change nozzel is awesome. Did a couple prints at 0.8mm and I was (obviously) able to cut my print times in 1/2 coming from the 0.4mm hot end. The provided tools work however you need a wrench or gripper while changing the heads to remove / install them. Don't over tighten, it stops when it's in.The issues I had were because my build plat was dirty. Cleaned it with dish soap, tossed it back on and I did some terrain prints for battletech. At 0.8mm on a Bambu A1 I was able to get reliable prints at 100% speed and it would kick up to 124% if you already had your base layers down. I jumped to ludicrous speed and tore up the build. I think I need to adjust the speed that the extruder functions at to keep up with the demand. No need to print at ludicrous speed on 0.8mm anyway.Compared my 0.4mm Bambu Hot End Speed printed terrain vs the 0.8mm max quality terrain (that was still much faster) and the hex based terrains (multiple elevations and such) are indistinguishable from one another. If anything, I think the stuff printed at 0.8mm came out better due to printing it at the max quality of that nozzel.

The 'intake hole' (not sure what else to call it) does not have the same filleted metal edge that the authentic hot end has and I believe this may be one reason why I got a clog only two prints after installing this which caused me to have to dismantle my whole extruder assembly to remove. I also noticed after taking this apart that the hot end tip where the wires go in did not have a clip to hold the ceramic heater and thermistor pieces. It also did not have any kind of thermal paste on it. It was just loosely fit in there. Maybe that's on me for needing to do that and not knowing but it came with the wire already assembled on it so I thought it was good to go...I'm using an official hot end now that had everything assembled including a bonus fan and throwing this in the trash. Would not recommend.

Seems to be working just as good as the Bambu Lab one. Would buy again.

I like to keep a few extra on hand & this brand has not let me down until this morning’s when it got delivered. I like to replace the hot ends when I start a really long build , but today I received a used one , with filament still stuck in the nozzle , this thing has been super heated to where the metal has even changed color . It could be an Amazon issue where they just accept any return and it goes back into stock . Other than that , I have no issues with the new hot Ends I get from here 5 star all the way .

Excellent product it works very well as well as the OEM product highly recommend faster delivery than the OEM product also.

Works great on my p1s.. forgot I've had it on for months.. no leaks.. prints are just as good as factory.. original part from bambu bent.. have not stress tested this one but it seems more solid
