## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, even on Anycubic Kobra S1 (after modding)
*by B***N on May 28, 2025*

Works very well! I bought it with the expectation that I would have to mod it to work with the Anycubic Kobra S1 and I did. All I needed to do was make the 3 pole switch either HIGH or LOW instead of just open or closed. I then connected the wires to the printer and it worked flawlessly! It took some research and setting up but not as much as I thought it would.

### ⭐⭐⭐⭐⭐ So much better than stock.
*by A***R on March 20, 2025*

So much better than stock. I have these on two Neptune 4 Max, on which the stock extruder is prone to the blob of death. The sensors detect both runout and filament movement. The Klipper tweak is available on GitHub, the whole thing took two minutes.

### ⭐⭐⭐⭐⭐ Saves the prints
*by A***Y on August 14, 2024*

This sensor really saves prints. I tried to print some dragon using Silk PLA and I failed three times due to clogging.I decided to upgrade my printer and install this sensor and for now it paused my prints three times due to clogging but I was able to resume printing after clogging. So I'm continuing to print.Minor issue with sensor - you will need to mount them - I found the custom mount compatible with my print head (ender sprite pro) and printed them.P. S. The above is definitely a filament issue. I printed a lot without any clogging but glad to see I'm able to overcome filament clogging issue with this sensor.
