i wouldn't buy one either. its no more effective then a properly fished $0.99 plastic minnow.
they can tell you anything they think you want to hear in commercials, and infomercials are no different. the banjo minnow isn't anything new at all, all of this stuff has already been around for many many years, and the banjo minnow company is just selling it for more by having a bunch of people swear buy it......seriously if the banjo minnow was so great, every pro bass fisherman would use one, but really if you watch bass masters or anything, i have never seen the banjo minnow catch anything, its always some simple cheap bait that is rigged and fished properly.
