They obviously work for 'ya Al.....seen pics of your sheep shot between the eyes! If I could shoot like that on a hunt I wouldn't use anything else either. Wouldn't want you shooting at me I know that much. Please understand I'm not bashing NF at all. They obviously have a heckuva product. My 52 year old eyes aren't good enough at dark thirty to reliably see all those hashes, dots, etc. I'm weird I guess.
With the illumination turned on, the reticles are easy to see in low light. The batteries last hundreds of hours on the lower power settings in my experience.
Thanks,
Chet
