swordfast review for DPO Dynamic Product Options

Of the many apps that I have searched for and tested, this is by FAR the most reliable. It simply has always out-performed any other for comparison. Our product can't be presented with complex options and so many permutations without this app. Good documentation, tutorial guidance, and efficiently designed code is an absolute must and Roman always comes thru!!! App provides a built-in conditional filter in presenting options that would make it easier for customers to select options. The support is great and Roman responds almost immediately which is amazing considering the time zone differences. His solutions are smart, concise, and bulletproof. I'm most grateful that I can trust his high ethical and work standards.
