Well, my experience with the Lumenoks has been vastly different than mobowhunter's. I've tried all 3 commercially made lighted nocks and the Lumenoks have been the simplest, lightest, and most durable of the 3. I just picked up 6 of them off Ebay for less than $40 shipped to my house. There is another alternative, make them yourself.
Are they worth it? I've been shooting them for 3 years and will never have a hunting arrow without them again. Why do we spend $$$$$$$$$$ on our bows and other equipment and whine about spending $7 on a nock that will help you see shot placement?
