The concept is interesting, and I don't know how many other extensions are out there like this one (probably a lot though), however, it annoyed me from the start. You need to login or get a 7 day free trial. I did the login and didn't get a quick email, so I had to use the 7 day free trial. It acts as a data scraper, which I could use, however it doesn't seem to update well. You can likely find better. It has inspired me to look for better.
