Could not be more happy!
I paid for the subscription to this site, so that I could access the early release of the product. Though it was still a release candidate, it worked very well. Moreover, the support from the maker is phenomenal!
I made a couple of mistakes in configuration, and they helped me through corrections. Even more important, they added a couple of features that I requested almost at the drop of a hat. Do not hesitate to use this product. It is money well spent!
