I run a business mainly on my personal FB profile, so this plugin is exactly what I was looking for.

I read the negative reviews and didn't purchase, so I reached out the support team to ask if the product was still being offered and supported. I got a response, took a chance and purchased.

1, The product works just great. At first I couldn't get the messaging to work but support helped me resolve this by simply selecting a different dropdown.
2, The plugins work just on a standard chrome, I don't use the beta version.
3, I installed the plugins directly from the chrome store.
4, The login information was sent to me in a separate email after entering the app sumo codes.

For me this plugin is a game changer, being able to follow up with leads in FB messenger makes my life so much easier.
