THe instructions say to make sure the limbs are warm (as in room temperature) so I leavethe bowin a nice warm room for several hours, then clean down the spot with alcohol and stick them on. They say wait 5 minutes then go shoot. I myself tend to wait at least an hour or so just to be on the safe side. I have had an occasional one pop off of a Parker since they come factory on them, but I am sure that is more of a prep issue than an issue with the limbsavers themselves. Somewhere along the line the limb just did not get cleaned up enough. I have also shot them in stinkin cold and unberable heat and not had them come off, so I am happy with them...
