I ordered a 3 pack of these a couple of weeks ago, and I just wanted to report that these are AWESOME!! They are brigher and more durable than Lumenoks, IMO. They are a tad tougher to install.....you can't just take them out of the package and put them in the arrow. You must first glue a small dowel pin in the arrow, but it is really easy. They add very little weight to your arrow, and show up nicely zipping through the woods.
I liked them so much I just ordered another pack today. Just thought I would pass on a positive experience.
