I got the other cosi cumo or whatever ones from amazon myself and after doing so swore off Halo. I went through 2 packs by the end of season last year because they all failed but one, and that one didnt explode but instead never lit.

 

I too have had great luck with the Amazon lighted nocks . Had one that I was just curious as to how long it would burn, so turned it on and still after a couple of weeks it was still dim when i tossed it in the garbage.
Good luck

 

I bought these work great ! Auto on switch for off no tool needed. 3 for 10 USD Free shipping CH to UK

 

All of those nocks I’ve tried off amazon work for about 3 shots then stop but then I read how everyone else has great luck with them. Any of yall shooting 80 or 80 plus pounds and using them? The halo has worked for me except the 2 that blew up out of 3 packs all the others still going strong..

 

I can't speak to the experience of others, but the Cosmi-Comu nocks that I have, I have roughly 50 shots on two different ones without any issues. I have some Nockturnals, and some other Amazon nocks and the Cosmi-Comu are brighter by a significant amount. At present, i'm shooting 63# with them.

Regarding your experience with nocks blowing up, by chance are you using 4mm arrows? Its my understanding that many folks have had issues finding durable lighted nocks in any brand for .166 arrows, which I can only imagine is compounded when shooting higher draw weight.

You bring up an interesting point regarding draw weight - I wonder what role that might have in durability of the lighted nocks. Shooting the draw weight that I do (63 - 67#), I haven't had any issues with durability of lighted nocks. Some have lasted longer than others, and some have surprised me with how long the battery life has lasted.

BlueCollarOutDoors on YouTube did a comparison of brightness of 1/2 dozen different nocks, and if I remember correctly he's shooting 83 or 84#. He's never mentioned any durability issues that I can recall, with whichever lighted nock he chose. He's responsive on his YouTube channel if you had a question about it for him

 

I use keaup without issue. 70lb and work amazing. I use them on my 3d arrows so I can see easier where I hit.

Battery life is not amazing. Had one i left on over night to see how long they go, and it was like 50% at best. So they do go dim.

Been shooting a set for about 8 or 9 months and are to thr point of needing replacing because they are not as super bright as new. Still work very well.

I've buried (accidently) arrows in dirt next to a target and couldn't find it for the life of me. Went back at dusk, and I must have walked by it 10 times and not seen it, but soon as dark came, I could see it 50m away. Well worth it.

 

I ran a lot of the 4mm red led red colored body Halo's. I broke quiet a few of them. For no reason. They fit my serving perfect, but everytime one exploded it would fit very tight on my serving for some reason. That is the indicator that they will break on that shot. I noticed the newer halos red, blue, and green all have clear bodies now. I have yet to break any of those. Maybe they changed their material.

I shoot a Darton 31 ST2 67/28 and I probably shoot about 100 arrows a day.

 

I've been using these off Amazon for a few years now and they fit great, fly same as my regular Blazer nocks, and are cheap enough that if one doesn't work or starts fitting loose/cracks I just replace it. I had Nocturnals start cracking after a short time practicing with them, Glory nocks didn't fit well and were really big, and the Deepower nocks fly terrible for me.

I'm using the Standard .245 size. The brand isn't always the same but they always look the same and have a small external switch. I had a couple that I re-used after going through deer with no problems.

Yeah - I gave up on Halo nocks - they broke far too soon. I've been pounding Keaup (Amazon) at the range and they keep on working. Turn them off with a thumbnail. I'm on my second season shooting some and they continue to be very bright - I think brighter than my Halo's or Luminok's ever were. Nock fit is good and the GT bushings provide a snug fit in the shaft (they can fit .204, .233, .244 and .246 inside diameter shafts). Can't beat the price, either. CosiComu worked well, too - I just didn't find them when I went to order another batch and found Keaup instead. I was never happy with the price or performance of Nocturnal, Luminok and other name brand nocks - especially the expense. Yes, Keaup nocks are made in China, but so was my iPhone. Don't confuse the price of Keaup nocks with quality in this case. You get both.

 

Cosmi-Comu nocks work for me. I have been shooting them for couple months now and zero problems. I have 5/6mm both. Red and green.

 

I have bought a couple dozen in various sizes from Amazon, zero issue with any of them. Shot the heck out of them last year, good as new!

Ran one through a Javelina and into the gravel and rocks, still going!
