I've been using the cheaper nocks for a while now, some of the nocks need the activation pin inside the nock filed down I use a nail a bit thinner than the bow string and then rap sand paper around it then sand the pin until it's flush with the base of the nock. I also activated a nock just to see how long it would last, it stayed on for well over 30 hours.
While trying to trigger the one knock, I was just waiting for that file to slip out and you stab you in the hand. I have been using a different "amazon" lighted nock and think they are great. I have left mine on after shooting and gone back the next day and still found them on and running.
