As advertised better value , fit and design than the original hot end! Works fantastic with my any-cubic vyper!

This works great for the Anycubic Kobra S1. I've ordered a factory replacement one under warranty, but it comes from China and I wanted to use my printer so I took a chance on this and glad I did. I can't attest to how long it will last but 3 weeks in and going strong with round the clock printing.

I removed the old hotend per the instructions on Anycubic's website. The install for this was easy and it seemed to match the dimensions and look of the original with no visible differences, at first. Once I installed it, I did a PID calibration on the printer as recommended by the manufacturer and fired up my first test print of a temp tower. After the first initial layer, the nozzle immediately began to glob out filament and make a huge mess of the next couple of layers until I manually stopped the print. I took it apart and removed the hotend and cleaned a ton of filament that was jammed in the nozzle. I reinstalled the hotend but what I didn't notice at the time is that the PTFE guide tube that had pushed itself out of the neck about 2mm. When I went to reinstall it, I did just as the first time and pushed up until it was flush and locked the lever back in position. It seemed to have tension when pulling down so I put things back together and fired up a second print. Same thing, temp tower. This time, it laid down the first layer nearly perfectly so I walked out the room. As I was walking away, I heard a loud grinding noise so I ran back in to see what was going on. The gap in the PTFE tube caused the neck to not sit flush and it was not fully locked in position so it had dropped down after the first layer and been dragged along my $35 build plate and dug huge holes and trails in it. I stopped the print, heated up the print head and removed it again and as I pulled it out of the print head, this time the PTFE guide tube fell completely out of the hotend and onto the floor along with a small piece of filament that was left inside. Now not only am I out a functional hotend but I lost a $35 build plate. I try not to leave bad reviews unless I have to and the second install was a bit of user error as I should have noticed, at the point, that the PTFE guide tube was not properly glued into the unit like the factory ones are but it certainly shouldn't fall out.

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.

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

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.

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