I use this piece of software on an Asus x52jc laptop:
- Core I5, 2.2 ghz
- 4GB RAM
- Cubase Element 7 DAW

I use it for sound design and mixing.

Performance and stability: 4/5.

Ease of use: 5/5 for someone used to manipulating EQs.

Basic manual (in Englsh only).

Efficiency: 5/5.

This software perfectly fits my expectations.

Pros:
- Sober, flexible and practical interface.
- The ability to listen and mute frequency bands.
- A very complete plugin.

Cons:
- The spectrum analyzer could have been made bigger.
