After using this cheat for ~100 competitive matches, I've decided to write a testimonial sharing my thoughts on the cheat.
I'm not very good at writing these, so please bear with me.

FEATURES: 10/10
In case you don't know, chams is basically coloured player models. I find it hard to spot the enemies in csgo sometimes, thus this cheat was the perfect solution for me!
The cheat comes with great customization. You can customize the following:

•  Toggle enemies
•  Toggle team
•  Toggle wallhack
•  Customizable shader type
•  Weapon chams
•  Disabled when dead
•  Customizable colors

The colours are bright and crystal clear! Just perfect!
You also have a "panic key" option, which will temporarily disable the cheat. This can be useful if you're clutching and your entire team is spectating you.
During my hours with the cheat, everything seemed to work perfectly. I didn't come across any broken features.

Note: The range of the wallhack-chams can be a little whacky on some maps. This is NOT PerfectAim's fault, it's rather how the game engine works. I knew this before I bought the cheat, but I can understand that someone who would use chams for the first time would complain about this.

SECURITY: 10/10
The security is the main reason as to why I bought this cheat. I feel like I can always count on PerfectAim when it comes to security.
I was in need of a cheat for my main account (steam level 400 with a ~$1000 inventory) and I'm not worried about any bans.

Security features:

•  Silent ring-0 injector
•  Unique builds
•  Screenshot cleaner
•  Minimal footprint (up to 90% smaller than a regular cheat)

You can get banned if you cheat obvious! Read about how to avoid getting manual banned here

CONCLUSION: 10/10

Top notch cheat if you have a decent aim and just want the little extra.
For it's cheap pricing, this cheat simply can't go wrong :D

nice and detailed review, truly  pleasure to read
