First I'll say it to get it out of the way...I'm cheap!! Ok with that said I tried them just so I could see if they are worth it. What hurt my feelings was when I would lose a rig. .75 for the force bead, $1 to $3 on a tungston weight, and the nice gammy hook for around .75. plus the plastic. (cost on the tackle varies) It felt like I was wasting my money.
I'll stick to lead and glass beads for c-rigs...JMHO.
