Price: $25 Amazon
Construction: 1 piece; air-pressurized plastic; very hard plastic
Pros: The Big Jack is a novelty bat designed to hit a ball far regardless of how hard you swing. Soft swings generate a lot of pop.
Cons: The bat is ridiculous to look at, and is very short (30″). The sticker fell off after about two swings.
Grade: C- (For sheer humor value)
