Everything works well as far as I can tell - we've been using it for about 3 years without any issues or complaints from customers. It's easy enough to use but also has some advanced features which are helpful when you need them. If there were more ways to show "unreviewed products" so people could easily see items they haven't reviewed yet. We have one feature where if someone adds a review, then our app will send an email reminder to their phone asking them to submit another review. This helps us keep track of new reviews since we don't want anyone to miss out on adding a good review!
