The component is really powerful and still quite intuitive. However, I needed to make a few adjustments to code, so I searched the Hikashop forum first, just to give it a try before spending hours on figuring out things. I found out, that the support from developer is stunning. People who asked questions of my interest got answered fast, their issues were solved in couple of hours. I spend just a few minutes searching and pasting code form existing threads.
I would like to thank the developer, even if I didn't ask, for the best support.
