Nothing but positives. We added this to our Gravity Form in order to obtain the dynamic math captcha. One can create a simple math captcha in GF but not dynamically changing for each form load insofar as I can determine. And GF google captcha Ver 3 is a pain with the need for google api keys.

So we added this plugin and it was very easy - add the captcha field to the form, select "math" in the settings for the field and done!

We find that Gravity Forms Zero Spam plugin was helping to deter spam entries but it with this captcha is 100% so far for spam prevention.

Thank you Takayuki Miyoshi!

Needed this for an installation with custom forms. I used the plugin developers instructions and was able to make a fully custom implementation based on server side validation within 30 minutes. No more spam bots misusing the forms. Thank you!

Worked great for me a a simple solution to annoying emails. looked good

Plug in is lack of templates and spam is continue to come...

Captcha so helpful as a tool for the spam protection. This plugin do everything what I'm looking for.

All set as should be, but after writing message I can send the message without captcha. It's there but without any function. Mailbots has no obstacle. I don't want miracles for free but at least some efect wooul be great.
