I shot a Zero Effect for many years on many different bows, the rest worked great. Only issue I have is thatit's made of plastic, and plastic breaks...I know because it ruined a hunt a few years back.[:@]The arm that holds the "hook"arm in place cracked, as I climbed into my stand I drew my bow back as I usually do, and the hook spun around. Lesson learned and I'llnever put anything plastic on my bows again.
