Dnk:

I have had a Quad 400 since they first came out. It is my first crossbow. Had a long learning curve with it. If not lubed often,the string will start to go bad in the center where it is seized. The cables will fray in the groove where they cross. Thestring will fray where it goes around the pulleys.

Killed several head of game with mine. It is now semi-retired. Now hunt with a Barnett Revolution XS.
