Well 2 years ago I tried the luminocks and they were worthless. I mean they only worked half the time and when the moment of truth came and I shot a deer the darn thing didn't even light up! Two days ago I got some easton tracer nocks and they work great and they work every single time. Then today I decided to give the luminocks one more try because they were supposedly improved and they now have them in green. So tonight I tried them and the very first shot I took they came on and as soon as they hit the target they turned back off. This went on for several shots. Finally they worked properly maybe a few times and one time that they did work I left the arrow in the target and took another shot and when my arrow hit the target a good 2 feet away from the arrow with the luminock on it the stupid light went off when my other arrow hit the target, I mean WTH! So I tried using the strips of paper that came with the luminock and I followed the instructions and it still wont work right. The thing that sucks is that I love the brightness of the luminock especially in green, I mean it is ALOT brighter than the easton tracer nock but what good is it if it won't work properly? The reason I love the green luminock is that I'm blind in one eye and I can see bright green better than any other color even when it comes to sight pins. I haven't tried the firenocks yet but Iv'e heard they are awesome. Are they brighter than the luminocks or the easton tracers? Also do the firenocks come in green or just orange? If the owner of firenocks reads this and firenocks don't come in green could you PLEASE consider making them in green? That green is just awesome in a lighted nock I mean you would have to see it to believe it. It's just so upsetting that the green luminocks are so bright and I can see them 100 yards away but they won't work properly. Sorry I just had to vent, I'm very frustrated.
