Yes I have one on my bow. It doesn't affect arrow flight at all. it will hold the arrow on the prong rest no matter what the position of the bow. drawback I recently found is when shooting small diameter arrows like the a/c/c's it works on the fletchings a little. I had no problem at all with the beemans or aluminums at all. Good idea that has been around for a long time. I have owned and shot with one for about 7 years now.
