It has long been searching for such a filter implementation for virtuemart, but so far both free and paid filters do not work correctly and functionality they have much less than that of the filter. VM Universal Search PRO pleasantly surprised by the friendly administrative panel as a component and the module. It really makes the correct selection of both the individual characteristics of the parameters of types and for all sorts of chords categories, manufacturers, price range, type. Very vivid realization of the slide image banding. And in addition say that the filter makes it easy to customize output style, the implementation of which is very similar to the inference virtuemart. If you are looking for a filter for virtuemart, do not pass by. Long hours of searching and testing other filters I have found that the best solution for filtration products on virtuemart does not exist today.
