HICTOP Ender 3 S1 Hotend High Temperature Pro 300℃ Compatible with Creality Ender 3 S1，Ender3 S1 Pro，CR10 Smart Pro，Sermoon V1, Sermoon V1 Pro 3D Printers

Had and issue with a ribbon cable going to my print head. Made a mess of the first one I bought. 1 ½ years ago. I broke it trying to clean it up. So I bought another one. Works great, bought another one to have on hand as a spare...Just incase.

It worked out fine. Wish it would have directions.

This assembly was working fine until something changed and it smashed itself into the print bed so intensely that it damaged both the bed and the nozzle. I found out that the screws that hold it in place had come loose, which I think lead to it smashing into the plate. Then, I tried to replace the nozzle and realized it is practically impossible to unscrew. It actually deformed the little wrench that comes with the ender 3 because of how tight it is. I would not recommend. find a hotend that stays in place and that can easily have the nozzle removed. I never had any issues like this with my old hotend.

The original one was broken and the replacement one broke in the same location in less than 2 weeks

Fits well in my Ender 3 S 1 Pro. I think it needs lower temp to print since initially I had a lot of stringing. Lowering the temp fixed the problem.

Great and easy to inatall

Some older filament broke off in my old hotend and I couldn't remove it. I had no choice but to replace the end. This one fit perfectly in my Ender S1.

Working for my ender 3 s1 but only 2 stars as it was missing the thermal paste on the temp sensor. This allows air to reach the temp sensor and therefore leads to less accurate temp readings, less accurate prints. Everything else seemed perfect however I'm not sure why they skipped this simple step. If they had i would give it 5 stars but its pretty important. For now running without the paste but will keep a eye on it. If i start see thermal runaway as some other reviews mentioned i will know the cause...
