What every best has:
In other instances, users and experts say the Ding King Twist-A-Dent does nothing. According to reviews, it seems to work best on shallow, uncreased dents that are no bigger than 6 inches in diameter and aren't near the edge of a body panel. Users say it alleviates some bigger dents, but it may leave ripples or small dents in the metal. Some say it takes hours worth of repeated tries to remove a dent.
Occasionally, users who buy the Ding King say the tool's bonding agent damages their paint. (One admits he didn't notice the warning that Ding King should only be used on factory paint.) However, expert testers do not experience any paint damage, leading them to conclude that it's worth a try, considering you could pay $50 to $200 or more to have a dent removed professionally.
Consumer Reports conducts a definitive test, trying Ding King and a competitor on dozens of dents. Unlike most Consumer Reports content, this report is free. KDKA, a TV station in Pittsburgh, also conducts an expert Ding King test with the help of a professional auto body repairman. User reviews at Amazon.com, InfomercialRatings.com and Epinions.com show the same pattern: The Ding King works on some dents, but not all.
Nineteen panelists try the Ding King Twist-A-Dent and a competing product, DentOut, using their own dented cars as test subjects. They evaluate the effectiveness of the two products on more than three dozen dents of various sizes, and also scrutinize the instructions for ease of use. Results are compared with the work of a professional body shop.
KDKA consumer editor Yvonne Zanos enlists a body shop owner to try Ding King Twist-A-Dent on several different types of dents. It works on some, but not others; Zanos concludes that it's worth buying to remove at least some dents. The video of the report is also available on the site.

As it does at Amazon.com, the Ding King Twist-A-Dent receives three stars (out of five) on this user-review site. Some users say the Ding King pulls out dents at least most of the way, while others say it either doesn't work or damages their vehicle.
Once again, the Ding King earns three out of five stars. The majority of users do notice an improvement after using Ding King, but many say it doesn't work as well as it does on TV
