Excellent
Very happy with it. Linked FB and Google and it all works very well. Also imported a csv of existing reviews. Took me a while to realize you have to approve the reviews for them to show up. But once I realized that, everything showed up as intended. The FOMO pop-up and Wall is worth adding an extra stack. Can't wait for video reviews. Overall, I'm really impressed. As another reviewer mentioned, if using Wordpress, search for the Header and Footer plugin for a quick and easy way to add the code.
Wishlist:
1) option in widget to show review card without the stars.
2) option in widget for no photo.
3) option in review form for people to remove photo after importing avatar from FB or Google. There is no way to undo. I think some people might just cancel the review if they don't like the way their avatar photo looks.
