6PCS G X H S GT Led Lighted Nocks for Arrows with .165 .204 .233 .244 .246 Inside Diameter,Screwdriver Included

Did not notice much of a difference when shooting these with my arrows the lights are bright they work well for sighting in the bow and just checking the accuracy

All 6 turned on and off multiple times just like they should. I accidentally bought the wrong size so I have ordered more of the right size. Like others have said, even if 1 or 2 out of every 6 don't work it is still a great deal considering the price of "premium" illuminated nocks that are still somewhat finicky. Will definitely be stocking up on these.

Work great, just like the Nocturnal lighted nock but at a fraction of the price. They are bright enough (not as bright as Nocturnal), but you can easily see them. Would recommend

For cheap Chinese lighted nocks they actually work very well, they are very bright, easy to turn off, and they hold very well onto the string in my pse. I have even been using them to practice with.

Great lighted nock, I haven't found any lighter weight, these average 17.6 grain, and plenty bright

Just ordered a third pack, overall good but several in this pack are to tight to fit my arrows and 1 broke trying to install. Be warned that apparently quality can vary a bit.

All lit up brightly and fit snugly in the arrow

*UPDATE* These nocks are great! I've only used them a couple times to start sighting in my sight but overall they are great. All but one of them weighed the same, I'm not sure why one was about 2 grains more than the others but it is what it is they have lit up every time. Relatively easy to turn off. There are no directions on how to turn them off but I figured out you insert the screwdriver tool and pry up to separate the light from the battery. Not too crazy of a concept. They fit nicely in my easton 6.5 arrows. They don't grab the string quite as much as I would like but I imagine if they grabbed the string much more it would pull the nocks out of the arrows as they are not a super tight press fit. Overall I'd say for the money these are well worth it and we will see how long the battery lasts.UPDATE** 8/11 Went out to shoot today and one of my arrows went a stray and as the arrow hit the handle of the target it flung the nock out of the back of the arrow and turned it off so now I cannot find it... that's kind of what you get for a nock that will fit between .244 and .246 but just a word to the wise take a plastic bag, like a ziploc, put it over the end of the arrow and press the nock in to the arrow through the plastic bag. This will have the bag fill any space gap in between the nock and arrow shift. Then take nail clippers and clip off the excess bag to reveal and clean and tight press into the shift. Hopefully it won't fly out this time!
