Bad results and out of context
I really tried to like this service because its price is low but it's really not good: When you do a keyword search you'll have to consume a credit for each keyword identified otherwise you'll get nothing: No volume, no CPC, no trend. In the end, for the price it's understandable - the big problem is that the answers you get are wrong. I don't know which third-party APIs they use, but not only do I not find the same information as with SEMrush, SE Ranking or even Mangools KWFinder. Okay, there's no comparison between the rates, but if being cheaper means getting the wrong answers, then there's no point.
To top it all off, when you search for keywords in a language other than English (French in my case), you'll get a list of keywords mostly in English or from another context (for example, if you search for "tech news", you'll get "new gum grafting technique").
And the slowness: 26 seconds per keyword to collect metrics! I wouldn't want you to have to collect a list of 100 keywords!
Combined with an outdated UX design, sorry, I'm out. On the other hand, for English-only content it seems to do the job (hence the two tacos).
