G Nock 4.2mm Lighted with 5.2mm Bushing for Arrows with .165.204 Inside Diameter Bowstring Activated Linear Switch LED Nock Tail Illuminated Lighted Archery Nocks (Green 3-Pack, 0.165)

I shoot the gold tip pierce platinum’s, .166 diameter arrows and these G nocks fit very well with NO play! The weight tolerance was 0.3 grains when compared with one another - great tolerances! The on-off switch is simple and works as designed! For the price totally worth the money!

I bought 2 packages since I needed 6 arrows. All would not fit in my v-tac 23s had to be slightly sanded. One broke on install, one doesn't light upon shooting, but can be turned on by hand, and one slightly glows after being turned off. The 4 that light up are extremely bright. It's a shame that half of them were defective in some way or another.

Theses are great. They are so cheap for how good they are. Being able to switch them off from the outside of the nock makes it so much easier than other brands. They aren’t super durable though. Getting out of my stand and lowering my bow i hit them off my stand and broke 2. At least it was at the end of the day. More my fault. But for the cost I can’t complain

They are bright and have a nice switch on them but 2 put of 3 broke

Upon receiving and shooting for a day only 2/3 light up. Kinda disappointed in that.

Got these because I refuse to pay $40 for other brands. The ones I got all worked perfectly. The quality is good. I liked the feature of having an external switch for easy on/off. However, I found that having that external switch turns the light off when you have a pass-thru shot. I easily solved this by removing the black slider swhich with a flat screwdriver. Now the light stays on until I turn it off with my knife tip. Very happy I got these. I bought more.

I purchased two packages - 6 total nocks - for practice only to make sure the weight of my practice arrows are the same as when I hunt. Two of them broke on install, while installing by hand, no tools. One of them I had to dig out of the arrow which is not advised since it's a lithium battery, but when a single arrow cost is more than the cost of the nocks I decided to dig it out to save the arrow.This was my second amazon purchase of lighted nocks, previous purchase was G-Archery which seemed FAR BETTER (I was happy with those) - but they do not make nocks to fit the 5mm Easton Axis arrow which has a smaller ID. These Ellen Archery brand nocks are very poor quality.Save your money and buy a quality name brand nock and save yourself a headheach or worry about ruining an expensive arrow.

I had my lighted knock already on in the box when I received it. Not easy to get new ones unless you send the item back and continue to wait for them to send you new ones. If it's already on they should automatically send you new ones. They do light up very well idk if the battery life is good or not yet. As usual they are easy to install.
