Pros:

Adds appropriate icon for the P90 Skin

Cons:

Horrible sound replacement, stick with the default or other. 
Sound is not edited correctly, has strange report and overall quality is horrible. 

Conclusion:

Use the icon, but not the sounds. 

Pros:

High quality
Absolute attention to detail
Amazing animations
A little less "tacticool" than other skins/models which I like

Cons:

None
