They are JUNK!! I bought a pack of 6 about a month ago and put them on my arrows, after 25 shots i had 3 arrows with fletchings missing and the rest were starting to come off! I learned my lesson!! I have heard from people on this forum that they are good when you are in a bind, say at hunting camp and you need a quick repair. That is the only time i will use the quick fletch again!
