## Customer Reviews

### ⭐⭐⭐⭐⭐ Nano Optics .019 Fibers
*by C***R on June 5, 2025*

I’m very happy with these fibers. They’re super bright and easy to work with. I’ll definitely use them again the next time I replace the fibers in a sight.

### ⭐⭐⭐⭐⭐ Color choice
*by J***S on September 29, 2024*

Yellow and green are the brightest for me to see.. green is by far the brightest. It appears to be 2x brighter than the yellow.

### ⭐⭐⭐⭐⭐ Super Bright!
*by V***G on March 2, 2023*

I have a bowtech SS34 with a spot hogg single pin slider. I like to work on my own gear. I wanted to change the color of my single pin...did some research and decided to go with these Nanoptics ultra super flex 12". Dang! they are bright....The original spot hogg fiber was almost 16"long and wasn't sure if this 12" would do. No worries....it works great....super bright! would recommend for sure.
