I will never understand how "Chams" works or what it means but I always buy wallhack tricks because that way I feel more legal and the truth is that I have been using this trick for more than 30 days and I bought it again for 30 days and thanks to him I have been able to improve reaction and even without having it activated. 

I am glad you are enjoying the cheat, I personally have never used the Chams but I have used the MultiHack. Since you stated you don't understand how Chams work it is pretty much just a wall hack to let you see your teammates & enemy's through walls.

Very nice review mate. Chams means basically only Visual assists (ESP) :)

Apart from giving you visual assistance, it helps you improve spikes and shooting reaction, it is a great help to be able to practice all spikes and at the correct level

I recommend that you continue practicing it, to be better in reaction and picks, plus the great help of the cheat :D

Chams are better than boxes becauses they make it easier to judge the distance
