Why is this Tool Better than Others?

Because instead of hunting for keywords that Buyers may or may not be using to search for your product, you can just get all the keywords that Buyers are Using to find your Product with a simple use of Your Top Competitor's ASIN. You may use your Products ASIN, but if it is not "popular" or if it hasn't been on Amazon for long you won't find many keywords, and many may not necessarily be related to your product.
