This is the first extension I have paid for and it has put me off paying for any more. I had problems with my install, found no documentation to help solve it. I asked for help from the developer and was replied to relatively quickly but he was rude simply because I did not want to grant him access to my site (is this a normal request?) When I finally got it sorted, I had another small glitch. Ultimately though when up and running it is an excellent extension and easy to use. Needs better documentation and service for paid extension.
