# FAQ

<details>

<summary>What is the difference between the Black Box and the Black Box Pro?</summary>

The **Black Box** is the initial version that we created. It was our first cloud sniper. Later, we created the **Black Box Pro**, which is a highly advanced version of the Black Box Legacy: with significantly enhanced performance, a more intuitive interface, and offering more control.&#x20;

We can only recommend using the Black Box Pro instead.
