They work but I haven't ever developed that confidence factor with those. You'll get lots of positive feedback. My brother (castman7) does well with chatterbaits along with lots of other guys on the site.
I have caught my PB on a chatter bait early this year. I had never used one prior to that day. It does work and I have caught several more smaller bass on the same bait with a different trailer. They are quite fun to use now that I have the hang of them.
