An endless amount of free content inside.
To break it down:
> Animated BG's
> Animated BG's with effects
> Animated BG's with music sensitivity (example: bars jumping up and down if music is on)
> Animated BG's with music
> Too much anime content for you weabs (lol jk)
> Does NOT hinder pc performance (keep in mind that my pc is high end though)

tldr: It is A HUGE BARGAIN for its $3.99 USD price. Or maybe because there are so many people dedicating their time and efforts to create beautiful backgrounds for us to enjoy.
