Does your lighted nock insert fit loosely when you install it into the shaft? I know they get glued, just curious if you had a loose fit before glue... Mine are loose but, they are the ones they said were for my arrows.
On a side note, my 6 pack arrived today, 4 already activated or dead.
Gonna shoot the an email or a FB msg and see what they can do.

You don't have to glue them in. Just put a sandwich bag over the arrow a shove the insert in. It will give it a tight fit and you can get it out later if you need to. As for the batteries being dead I'm sure they will make it right for you.

WOW, they are fast to reply to emails. Loose fitting before bonding is normal and, replacement lights going in the mail. Good to know the customers services is top notch.

NuFletch folks are good people.

I like the sandwich bag trick! I'll try that next time instead of glueing!

Also put a little bow wax or chapstik on the nock and it will create a water tight barrier to keep blood or rain from getting into the batteries.

Mine are loose and my buddy's too. I'll have to try the bag trick. I've seen the Nufletch folk drop them in a glass of water and leave it. Good to be cautious but I don't think that moisture is a concern for their product. Also, I find green the easiest color to see. I switched from the red. Green is much brighter.

Guys, these nocks are the most durable lighted nocks I have ever shot. I shot lumenoks for two years in Buckmasters and had several that the battery would come out inside the arrow. Others just wouldn't light up. I've shot the same 12 ignitors the past two years at Buckmasters and haven't had one that didn't light up. The first year I practiced with them for two months turning them off after every shot. I probably had 150 shots on each arrow with no problems. Last year I just took the batteries out while practicing. During hunting season I swap them over to my hunting arrows and have killed quite a few critters with them. Just remember if you break a nock or insert nufletch will replace it for you.

I shot both the Nufletch and Nocturnals the other night. Nocturnals were a little brighter. The Nufletch are a little lighter in weight. The ability to remove the light stick from the Nufletch is a plus. I like both but, you can't beat the price on the Nufletch with the code Shaw put out.
