I dont think you´re right. All PerfectAim cheats are very easy to configurate. Im also pretty sure the aimbot isnt shit. If you have problems or do not understand something, make a thread and simply ask. There are many users that are willing to help you.
Making a bad testimonial isnt a solution. It doesnt help you and spreading informations that are maybe not right doesnt help others either.
I understand your pain, I once bought CS:GO cheats but as soon as I loaded the cheats it wouldn't let me connect to a game. I asked for help and the person helping me never responded to anything and actually closed the discussion saying that it was resolved. This made me extremely mad however we also have to keep in mind that its not always PerfectAim's Fault. It very well could be due to human error, I could have downloading something the wrong way, you could have possibly done the same thing. Just keep an open mind and ask the community. The PerfectAim community is one of the most positive communities I've ever dealt with. This could be due to everybody trying to rack up reputation points but anyway, what I'm trying to say, is just keep an open mind and be positive!
