Domain Hammer

I see there is a firefox plugin that has Domain hammer, Im not sure what it does and was wondering if anyone knows any information on that product.

Look here http://www.domainhammer.com/seo-analysis

Would't have been simpler to just google it to find out? Oh, then you couldn't promote it.

I know the basics of what the website says. but if i visit any webpage with the toolbar it just says ""no"" beside the domain hammer. so i was wondering if it was a feature that said if the domain in question was banned or not. all in all the rest of the toolbar/plug in is quite handy if your looking at expired domains.
