Nockturnal X-Nock

So i use this as single use on my .204 hyper flight arrows. They crush when you shoot them but man it stayed lit up bright green from thursday at 1pm to Wednesday morning at about 11 am.

Great nocks - must have slightly changed the design though, a touch wider than an actual
X nock is now

2 out of the 3 were so dim they were unusable for a lighted nock. The third was bright and only lasted one practice session before going out. Guess Im SOL and have to use them as practice nocks since they don't make any anyway. Strange how they are so bad right from the manufacturer. When I have ordered from amazon I haven't had any problems. Pretty much $10 a nock and they don't even light. What a waste.

Bow: Yellowstone Custom
Arrows: Bloodsport Onyx .165
Arrow Weight: 495-520gr

Knock lit up great but after a few shots my arrows started dancing mid flight. I couldn't figure out why and upon further inspection I found that the knocks were actually bending. I could "straighten" them shoot once and they were bent again.

Super disappointed and cannot trust these in the field or on the range. Hopefully this helps prevent someone from damaging their bow or missing an opportunity on their game.
