Other than the Learning Curve..

I have been using this since about last July/August 2013.

As the other reviewer pointed out, if your not familiar with adding code to php files in your child theme, you will need to understand how to do that first. It’s not hard to set this plugin up and it is still working in wp 3.8.

My only thought with this addon is that I’d like to know if it’s actually working. Since I can’t test buy something from Amazon, I have no idea if the plugin is actually working, nor do I know if anyone actually clicks on the ads, so I’d love to see some kind of counter inside the admin to at least know what’s up, but otherwise, this addon is nice and is the only affiliate addon I found still working for posts and pages on wordpress.

As a side note here, if you change your theme (like I just did) you will have to add the line to the php file again, so this is a reminder that you’ll want to be sure and remember that about this plugin. If your theme has an update it will also need to be fixed in the child theme.

Edited to note the update of versions, still works as of 4.2.2
