Nice plugin, good support, and the only Pin-it plugin worth using. I've tried them all and this is the best. The others all caused various conflicts in my site, and I have plugin heavy...almost 60 plugins...and this one blends with zero conflicts.
Also, it's really easy to select where you want the pin to show up, image sizing minimums, custom pin images, and also location of the pinit button on the image.
I'm using the pin-it button in a unique way, as I have created a series of pin-boards that promote the collectible resource listings on my website. When I add a new listing I pin-it to the board. This is a great traffic driver.
The only feature I would like to see added to the app...it only allows for personal FB pages...in the future it would be great if I could use the FB post option to also post to my FB Business Page.
