Houkr New Upgrade Metal Hotend Kit Filament Thermal Heat Break for Creality CR-10 / CR10 / CR10S / Ender 2 / Ender 3. (1.75 mm)

For the price, I can't give this less than mediocre. That said, I can complete 1 print on my CR-10s and after that things clog. All parts are different than other items I have. That said, everything fits beautifully to my unit. Maybe if I spent another few days trying to figure out the issue things would work perfect. If you have time to work on debugging like I did a long time ago, this unit is for you. Meanwhile, if you are looking for something to just work, this thing is $20; what do you expect?Amazing price. Excellent quality. Just needs some tuning I don't want to deal with after spending all day debugging servers for a large online company.

built quality is poor, for the price its not my main concern. The deal breaker for me is the inability to print PLA. During the assembly on my Creality Ender 3 it jammed, I thought nothing of it and then on the first print it jammed again. The heat is traveling into the throat and melting the filament there. I spent 2 hours in total installing, then pulling it apart to clean it twice and then removing it again and installing my stock hot end.

I bought this for my Ender 3 and it jammed on the first print. It has to small of a feed tube and it does not say hot enough to print.

it seems the machining between the nozzle and the titanium extender was not right, the nozzle would constantly back up.

Worst design. Filament stay stuck and melt in conduit to tip

Pure trash.

This hotend is trash, every time that you try to print is a lost of time and filament, always stuck in the print proces, good temp and retraction, but the design of the heartbreak is trashed.
