These nocks are fantastic! The durability appears to be right on par with nockturnals. I use them for indoor shooting b/c i don’t hunt so it helps me to see where my arrows fly.

These are just as bright if not brighter than the rage's. They are decently bright for when i have used them. Very comparable to the nocturnal's but comes at a much better price.

They're not nearly as bright as nocturnal that i've used in the past. Greatly diminished illumination, especially for green. The issue i have is that they are noisy.

Lights go off when a button is pressed by the bowstring inside the nock. If you move much the arrow comes off your string. When you slide the collar up, more often than not, it will slide back down and the light comes back on.
