This is an awesome replacement for the stock A1/A1 Mini hot end! If you install it correctly and properly lock the heat block clip, it operates perfectly. Note: If you screw in a nozzle and tighten it up then install it while cold and start printing, or you just install it new out of the shipping box and start printing like you would do with a stock hot end - the heat block threads will expand when it's hot and may leak melted filament underneath the silicone sock and make a big mess. Instead, be sure to follow the included instructions which say to heat it to 200c after installing and then --carefully-- use the included tools tighten the nozzle **before the first print**...(not super tight, just nicely snug). I would also add, don't touch the tools on the heat block/nozzle for more than a quick second because they too will become very hot, very fast while you're tightening. Highly recommended!

This hot end is working fine in my Bambu Lab printer. I like that the nozzle comes off for cleaning but I cannot find replacement nozzles to fit.

It worked great, but I found removing the nozzle tedious. I much prefer the solid hotends from Bambu. I keep this one as a spare because having the separate nozzle to deal with is just a pain. When you tighten the nozzle the stem can shift from the main block, and then you have to realign it so it fits properly

So far I've had no issues, the brass means I save time on warm up and cool down during prints. Worth the price.

Worked for a couple prints, but the head won't stay in place. This causes bad prints and at one point caused my a1 to not level correctly and the nozzle dug into my build plate completely ruining it.

At this point I have several of this style of 3rd party nozzle. I like having plenty of spares, and these are affordable, and swap out just as quickly as the OEM hotend. I have about 30 hours on this hotend so far. I changed no settings, and can't see any difference in performance versus OEM. I love having the ability to buy cheap nozzles instead of replacing the entire hotend.

You are more limited by the filament melt rate than the hot end on the A1/A1 Mini so their claim of it being a "speed" is purely marketing fluff. There isn't anything special about the nozzle itself to increase melt or flow rate. It is a tighter fit than the stock nozzles though which can make putting it on or removing it more difficult for no real needed reason. This is due to the cooling fin section being ever so slightly wider and edges sharper so they don't smoothly slip into place. If you need a cheap replacement this will work, still prefer OEM myself though.
