I had originally bought the chams by accident but decided to try them out, I've loved them and have been using them for a few weeks so heres my thoughts!
To start out here is the menu:
As you can see it has all you need to play legit and will give you the upper hand you need in game!
You can have different colours for enemies in cover and enemies in the open and the same goes for teammates, another cool thing you can do is set different textures from a clean and smooth texture to a wireframe. You can have it so it only shows the visible parts of the players or only shows the hidden parts of the players which makes this cheat very diverse in the ways you can make it look.
Heres a picture of it in game:
You can really see how much you can customize the cheat to your own style and preference, If you are looking for a cheat that will give you the advantage in CS:GO this is it. The only thing I wish I could do with it is use it with the multihack. If I could combine both of these cheats it would be the perfect cheat!
