I hired someone to created a site for Canada a couple years ago, which needed to be added to my US site. So he use some plugins to duplicated everything, which ended up as a mess. I have to separate the CA site from my US one, then left everything duplicated - with the same URL! When I tried to manually delete one page, the other page was not working. I was so frustrated and mad at that guy who created the problem for me. When I found this plugin, I decided to give it a try. So I installed, activated. Here is the result: 83 duplicates found in 0.056 sec. Mem usage: 16 mb. Then I click Delete, it took 3 seconds to delete those duplicates, and MY SITE STILL WORKING PROPERLY! Such an amazing plugin! Thank you so much to fix my headache!

An errant import created triplicates of hundreds of Event Calendar events. This plugin allowed me to clean up the mess in less than 30 minutes.
