I bought the 3 day trial and so far I'm loving it, the GUI is great, there's lots of customizable options for the optimal experience.
The Aimbot is great, it works perfectly but I wouldn't recommend going crazy with it. I usually have my smooth aim on as well
The ESP is great, I usually keep it on 2D rather than 3D because it makes it easier for me, and you can customize all the colors for friendlies and enemies.

Cannot think of anything bad about the product, it works amazingly well and the programmer has clearly done a great job!
