I've tried multiple multiple cables, all were at best mediocre. These are hands down the best I've ever had. The combination of fiber optic cables is genius! I'm going to be installing these on all my handguns! I have fiber optic on my bow so I was familiar with that, but in low light conditions when the lights up... it's Amazing! FOS provides a great range of cables & networking cables. Thank you for such a great products!
