I installed the mod and did the neccesarry configuration total time 5 minutes with some checking/testing.

I had to edit the Language files because of a translation error but the developer is going to update that.

Also I had to create the language specific file for dutch (root)/language/nl-NL/[nl-NL.mod_vm_live_product] because it was not included. The file holds the messages that are displayed like [Search.. 3 letters min]. It takes like 2 minutes and is easy to do.

The bad!
If the search does not show any result it defaults to the main page. the developer also says this on his site but it is something that needs to be solved. If you are searching in a shop you want to stay there and not get redirected to another part of the site.

This is an extension that works fine for a small site and is fool proof for Newbies. Try it
