I have a few mixed feelings with this. Their keyword analysis, growth potential is one of the best hands-down. However their competitor analysis differs in real-time. For certain keywords their tool shows the competition to be high, whereas a few backlinks easily pushed our website up to the top. Maybe it's just too hard to crack Google!
