PERFECT
these are the best lighted nocks i have ever used, and i have used some big name brands that were much higher priced and not near as good. easy to install with the different inserts, dependable and reliable. they light up ever time and stay lit after the impact. some brands use the conductivity of the arrow itself to illuminate the nock, which is iffy depending on the arrow brand or type. these work. every time. every shot. at the time of the shot, during flight, and after the impact or pass thru. they are highly visible even in broad daylight. makes finding arrows or bolts easier to find after a hit or miss. i use these on both my vertical bow arrows, and my crossbow bolts. they are reasonably priced, last a very long time, durable, reliable, and the only lighted nocks i will use
