This plugin mostly works - my Pin count shows up sometimes but most times it does not.
I followed the developers instructions for properly asking for support, but they never replied.
3 out of 5 stars because the plugin has glitches and the developers won't respond to properly submitted support requests. I have also let them know that I'll adjust my review if they respond.
You can read my support thread here and judge for yourself.
Here is the thread of me reaching out to the developers on Twitter (which they instructed should be done).
