Its look and feel is quite effiicient and when you start using it, you realize it's pretty easy to use and it works really fast. That's the feature we like the most, it's fast and loads the documents in a really short time.
Furthermore, it doesn't consume a lot of resources so you can enjoy it even if you are using a not-so-new computer.
The rest of features and options are the same other PDF readers include, such as multipage, image copy, or text selection.
In short, Free PDF Reader is an useful application for any user who don't mind uninstalling Adobe Reader and try something fresh like this.
