Not the Cleanest Plugin, but DARN GOOD!!!

So, it could give you more flexibility and fields to play with. However, if you want a simple tool to filter out the humans from machines, this baby works.

Positives:
IT WORKS
No Fake free then upsell.
Code is very simple.

Negatives:
Limited in the flexibility.
Documentation is limited. (Example Google calls the Keys differently than the application)

1. SITE KEY (public key)
2. SECRET KEY (Private Key)

Still compared to the others this works well once you get over the hurdle.
