What is the URL? If they are offering top keywords for $$, I wouldn't trust it.. you can snatch off a free list online.. and you'll find out not all of the results are true..
I've used it before, for a job. We didn't use all the functionality of it, but it doesn't do much beyond provide a list of top search terms for certain dollar ranges. There is no way to tell if the information is accurate and for what keyword market it is reliable to compare it with. Keyword country also felt like a scam because we paid a decent amount of money for it and all you could do was get 1500 keywords per day (that was their limit). They would do updates and there was nothing different with the program. There's a lot of scams out there in the keyword list market. Beware.
