WooCommerce Product Reviews Pro Features:

    Customers can “watch” any thread to get notified of replies to the contribution
    Customers can filter reviews by star rating, i.e., show all 4-star reviews
    Optionally enable other discussion contributions, such as questions, standalone photos, and standalone videos (no ratings) along with comments on these contributions
    Reviews list added to manage reviews separately from blog comments
    Choose to set a threshold of reviews per product to avoid showing reviews while you gather feedback
    Ensures customers don’t leave duplicated reviews — enable updating reviews for a product instead!
    Allow customers to attach photos and videos to reviews
    Users can flag reviews that need to be moderated to alert shop employees
    Create review qualifiers to prompt customers for specific information and product feedback
    Includes structured data mark up for rich snippets in search results; stores using WooCommerce 3.0 will use JSON-LD schema markup
    Creates upvoting and downvoting systems to determine helpful reviews or contributions
    Optionally add badges to admin or employee responses or contributions to designate them as “official”
    Includes support for Product Vendors to let vendors approve and manage flags on their own reviews
    Display login buttons from WooCommerce Social Login on review login forms
