I picked this up primarily for keyword research purposes. I haven't had time to delve into it too much, but I recently tested it out for a friend who makes wooden kitchen utensils and wondered if SEO would be worth investing in.

It took about 2 minutes to figure out the tool and start the report process. 5 minutes later I had her supplied keywords in, and the apps suggested keywords selected. 2 minutes after that I had downloaded the report as CSV and was able to confidently tell her that she should invest her time/cash into social media instead of SEO. As a bonus, it also spit out the average CPC for Google ads for those keywords which are handy to know.

So far I am happy with the ease of use and the output of the KW research portion of the tool. But, it only seems to be useful for country-specific or global searches. It doesn't seem to break down by state/province, region or city which is very limiting for Local SEO for example. Hopefully, this will be an improvement in the future - which is why I gave 4 instead of 5 tacos for now.
