I've had no problems with it, works great.

After having been thrilled with the performance of my Kobra 2, I noticed the print quality begin to decline.Long story short, I mistakenly got this in hopes of modifying it to take regular volcano nozzles, and after realizing some goofs I had made, I decided to just install this piece.What a difference!Yeah. I could have gotten away with just cleaning the original one, but I had managed to bake some filament in there pretty well.Anyway ... Get one of these, or clean up they one you have. Slapping a new one in there was quick, easy, and painless.

First print with the new nozzle was fine. Second one started to show some artifacting so I ran calibration and adjusted some settings. Third print failed, filament was not laying properly. Took off the rubber sock covering the print nozzle and the entire bottom was covered in filament so I took the whole print head off and removed the nozzle. The top of the item was also covered in filament. I tried to scrape some off but even using acetone to soften the PETG, the little yellow nozzle piece snapped when I tried to unscrew it. Might as well pay the tariff surcharge and wait the week to get it directly from AnyCubic if I can only get one good print before the print head decides it doesn’t want to work.

I have found it just as easy to buy the whole hotend and swap out the old one after a major clog because its just 2 machine screws and 3 wires it takes less time than doing a nozzle change and cleaning of the heating block and with this u get a new teflon tube and new thermistor and everything it prints so nice after a hotend swap out if it majorly clogs again im gonna just get this hotend and make it like brand new so easy. I love it.

First one sent was used and very dirty. Second one was clean and works great.

The hot end on the FLSUN Q5 is cheaply made. It looks nice but after a few dozen prints it will fail. I replaced it with the UniTak 3D V5 . It's not an exact replacement. I had to mill off A LITTLE of the opposite sides of the heat sink fins to get it to fit between the two fans. It could have been done with a jewelers saw or even carefully with a hacksaw, possibly even filed away but I had access to a mill of sorts so I did it that way. Also two tiny holes need to be drilled into the bottom fin. Make sure the flat sides you just cut are aligned properly between the fans before you mark the holes or just have a couple of extra holes. Don't cut off too much fin as they must cover those tiny mounting holes.

Perfect fit for my anycubic vyper. Works great, I have bought these several times.

works great put it in and my printer is working like new again.
