After testing several ad management plug-ins, we came across this one and breathed a sigh of relief! None of the others provided the customization and tools we needed. We thought we were going to have to hire someone to code a plug-in from scratch.
There's a bit of a learning curve but once you've figured out how to use this, it's very easy and fast. We'll be upgrading to the pro version, this week.
The support is very good, too! We had a question about the plug-in and had an email answer within just a few hours. That's not typical when doing business between someone in the US and the Netherlands.
All-in-all, an outstanding piece of work. We highly recommend this plug-in and those who developed it.
