Newbie questions

Couple of questions before I make my first purchase.

I'm looking to use this for minimal cheating, nothing too suspicious.  
How long would you say a VAC ban would be avoidable using this cheat?
Also, how would I check to see if this cheat is detected or not?

The cheat is undetected since long time. There is nothing that you have to worry about. To check if a cheat is detected, you can check the VIP Panel.
