Very consistently good
I had no expectations from ordering from this company because normally I order truglo or Shibuya for my fiber optics in my scopes. I was surprised to see how consistent and high quality the fiber was when I replaced my factory fiber on my B3 scope. I've ordered a .010 and a .019 and even the smaller size gave a bright dot when inserted into my scope where the default factory fiber was pretty dim. 100% would recommend.

Fluorescent orange fiber
Very bright and high quality but definitely not orange. It is identical to the red fiber I have on my sight already.

Very bright, worth the Upgrade
First off the Hunter orange will look pink when you see it coiled up.The fiber is easy to work with and is very bright, I installed it on my Fast Eddie XL and I am very happy with the upgrade over the factory Orange

Bright and flexible
Flexible and seems strong enough. The full fiber i ordered was able to fit into my single pin sight. The battery is half dead and its that bright.The pink/red gunk on the fiber housing is something that spilt onto it.

Great product, very bright and flexable
Great product to replace broke or missing fiber optic tube in your bow or the rear sight assembly of your air rifle or powder burner.For air rifle and powder burner rear sights, cut off a piece 1/8 to a 1/4 inch longer than the tube you are replacing, hold tube, pass lighter quickly over one end, may require 2-3 passes, rolling tube in your fingers until you see a small round bulb form, insert tube into sight assembly with bulb facing towards rear, use lighter to melt other end at front of sight, the bulb on this end may end up larger, but that's ok, it will collect more light and it will also tighten tube in rear sight assembly.Do not use direct flame, it will soot up end of tube, just pass lighter close to it, the heat radiating from flame is enough to melt the end.It may take a try or two, but you will end up with very good results.

Very good product!
I ordered this for a CBE Tek Hybrid Pro with .010 pins. One strand of this nanoptics fiber was more than plenty for all three pins. I am very pleased and will be using this fiber for any future replacements.

Just what I needed
Worked fine to replace a single pin sight that had a coil of fiber. Was a bit tricky to manage 10+ inches of fiber but the product worked fine and did not kink or break.
