Not worth the money.
Getting many callback and CP errors when Apantic servers are down.

The button addon is "hidden" among other buttons so most users just don't use it. Some ideas were suggested here, but make no real difference:

Best answer style looks quite old-fashioned, it would be nice to get a more modern output.
The developer sorted the compatibility problem with Quick Reply for Guest addon. To be honest, that's the most positive part of this addon: developer always reply.
Just expected no problem at all from an expensive addon like this one.
Furthermore, £50 are required to remove branding.
I did ask you specifically what you suggested us to do, and you said you weren't a designer. I don't think you can blame us for not implementing change if we don't know what you want [https://www.apantic.com/threads/best-answer-roadmap.75/#post-510].
New output is planned for 2.0, but again, I'm not sure what you mean and we had no suggestions indicating a new layout (other than from Alfa1).
Other than that, I can't really address the cost of the branding. Branding removal is standard and it allows us to sell add-ons cheaper, allowing prices we lose selling add-ons for cheaper to be made up by branding removal licenses.
I'm sorry you didn't fully feel the product was suitable for your needs, but as always, we'd be available to hear your feedback.
