This is so far the best pixelbot I've tried used.
Payment is easy as they also accept paypal or credit cards. You pay and get activated on their website. There are instructions and also videos on how to setup and use the cheat. The admins are very active and communicate much with their customers.
The quality of the script is very good.
I use this settings:
Color purple:
FOV 60
Speed 0.3
Aim offset: 10
(at best you go in test match and find your best settings)
HypeX is very good!
