I went through the trial period to "test" the product to see if it was a fit for my client, it seemed good but i had some questions, so i figured by purchasing the full edition i could get these questions answered, after-all, it is one of those little bullets listed next to the purchase price. Its been over a month since I've submitted my questions and still no answer. Not even a recognition of my existence as a customer. I've had poor support by a few component suppliers, but I usually at least get a mandatory "we are reviewing your question" response. I can't recall ever being ignored by a developer like this.
I believe they deserve 3 stars because the component itself is good. Even the documentation on the site is good-enough to solve most issues. the problem is direct support and customer service.
