I use and love my GKF Mirage BUT as with ANY rest with moving parts you have the potential for failure!!! I think that's why full containment rests like the GKF Shoot Out have become extremely popular. I have heard many people state their problems and frustrations over numerous differnt models of fallaways, BUT I have seen MANY more shooters that have praised them and have NEVER had a problem with 'em. Like I said, the ONLY way to eliminate the chance of a moving part NEVER failing is to REMOVE the moving part all together. Try the Shoot Out.
