I decided to give this a spin because I loved its magnifying glass icon. Turns out it does research into Amazon with laser-like precision, like a magnifying glass refocusing a ray of sunlight into a blade of grass. One thing I liked most is that it shows all the information I need, like competitor's price, competitor quantity, and item conditions in one pop-up window. It also looks at all search results pages instead of just one, as one of its competitors does. Most of all, you only need to do 1 search in Amazon, click on the Tool, and the information is displayed in a very convenient spot. You can even download the results into a comma-separated spreadsheet. Premium users also get to add Product Notes, a very handy tool that I think justifies the monthly that goes into a premium account. Install this one to your Firefox (there's one for Chrome too), and you won't regret it.
