I'm very happy with the extension. The strongest points for me were:
* intuitive interface both for the customer and as well for the shop owner (using fast seller)
* filters can be translated and hence it works for any multilanguage shop
* helpful and quick support via galt
* Thanks for great support!!!
I bought Simple PopUp (Disclaimer version) and can say - IT works great!!!
I've had some problems whith my template, but owner supported plugin as he could. I want to say - great EXTENSION and best support!!! Thanks!!!
