## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, even on Anycubic Kobra S1 (after modding)
*by  on Reviewed in the United States 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.

### ⭐⭐⭐⭐⭐ Best Filament sensor!!!
*by  on Reviewed in the United States May 24, 2024*

I used to have a filament sensor that was made from an old endstop that seems to work half the time. this new btt filament sensor works everytime, it also doesnt matter what direction you feed the filament in which is a huge plus as my old one only let me feed it in 1 direction. It only took 5 min to install including the coding i had to do for klipper!!!!

### ⭐ Poor Quality
*by  on Reviewed in the United States February 24, 2026*

I have had two of these defective right out of the box. I would not recommend. The first one the encoder would not work consistently. I spent hours trying to figure it out until I replace it and the replacement worked fine. The second unit the switch circuit would not function. Unfortunately, my current setup and programming is designed to use this product. But, I will be redesigning to use something of higher quality.
