In theory it's a great plugin. But it's not particularly user friendly, and the lack of documentation as well as using different terminology to Dribbble makes it tricky to get working. Dribbble have actually changed their API within the last couple of years which makes it even more confusing to setup (is it V1 API or V2?).
I tried both, but I haven't been able to get it to work since I bought it, and they don't reply to emails or issues on their forum (we're talking months/years, not weeks) So unfortunately, at least until I can get it working, I can't leave more than one star.
