At $3.99 a pop, it's a can't miss. Just based on the description alone, I would pay twice that price:
"Yum® Dancin' Eels wiggle temptingly as if to say, "May I have this dance?" More often than not, fish oblige! The productive Dancin’ Eels combine the wobble of a crankbait and the free motion action that only plastic lures provide. Every jerk of the rod tip or turn of the reel brings the Dancin' Eel to life! Plus, it's designed with a refillable internal scent chamber to make the lure even more irresistible. Comes with a #4 in-line hook. Length: 6''. "
They suck.... If I were you I would never ever ever buy one. EVER!! Ok seriously, I have used these and caught some pretty nice fish on them, both smallmouth and largemouth. Anyway, my two cents.
