Hi, Daniel.
I was able to get results by using the shortcode you posted above. You can see the test page I created with your shortcode here:

The error you’re receiving in the source of your page (“ScrapeAZon did not find any available reviews”) might also occur if your server is not able to send HTTP requests to Amazon.com, which might mean that something about your WordPress/server/PHP configuration is preventing HTTP requests from your site to other sites (such as Amazon.com).
In order for ScrapeAZon to communicate with the Amazon.com API, your server/PHP installation must either support cURL (preferred) or HTTP requests through PHP’s file_get_contents function. You can toggle between those two functions by using the ScrapeAZon settings page.
Just in case, you should also verify that your Amazon API key and all related information is correct.
Hope that helps, and please let me know if I can be of further assistance.
James
