The extension is one component (with few but precious options )one module with a lot of options (this is where you will work mostly) and one plugin for the ajax calls.
It is fast and works very good.
Remember to check the menu item if you need to change the products in a row number!
I bought from breakdesigns another extension and i can say that I am a really happy customer.
The filters work like a charm. Very easy to use and very good product and also a fantastic support.
I have asked for some modifications and i got a response very fast with all the changes i requested, i am so pleased that i made a donation even if i had bought the products. People like Maks, must be helped in order to deliver to all of us such great tools for our websites.
