Before i purchase CS:GO cheats

Before i purchase CS:GO cheats i have a few questions
1. Do i need to disable anything before i can use the cheat without getting banned?
2. Is it currently VAC detected?
3. Will rage hacking give me an Overwatch/Untrusted ban in casual?
4. Is the skin changer currently detected?

1. no
2. yes, last detection was on 11th may 2015
3. use anti untrusted and play legit as much as possible.
4. no

1. There are some features and anti aims that are detected but they are always disabled when you activate anti untrusted. So no you dont really have to care about that.
2. It isnt.
3. you shouldn't rage too much in casual and you only get an untrusted ban for using detected features.
4. of course not.

Thanks, I should be buying it later today :D
