I was receiving 50+ spam registrations a day and this plugin saved me. The support team was excellent in helping me realize I needed to enable a few setting to get this working for my needs but as soon as I enabled those settings everything worked great. Very happy with this.

For the past week, my site has been inundated with fake account registrations. Since adding this plugin yesterday there haven’t been any new ones. I’m hopeful that it won’t cause any problems for students signing up for my courses.

Had an issue on the Registration Form of a multi-site installation, where the reCAPTCHA field wasn’t being loaded and displayed, after a major PHP / WordPress upgrades. Robert and his team promptly helped, with active support and genuine interest to figure out the root-cause of the issue, and fix the problem. Thank you!

I started using the plugin a few weeks ago and it did not work right away, since we are using a special theme. After contacting the support team, the issue was resolved quickly, even thought it was a problem, which was no easy to find. But the support team was quick, very friendly, brought up some good ideas and solutions. I can recommend using this plugin!
