Definitely love these nocks! I cannot attest to their battery life as I have only used them for a couple of hours at most, but so far they are working great. The light is very bright and I have not had any issues with them not turning on upon releasing an arrow thus far. However, getting the nocks to "turn off" is a bit difficult. It takes a good amount of force and the only nonspecific "tool" that I have found to work consistently well is a tip of a small knife. Other than that, great product! The GTs fit my Gold Tip arrows perfectly and I haven't noticed my arrows flying any differently in comparison to when I had the old nocks on. As long as the battery life is solid, I will certainly be buying more.
