Im with HYPEX for months got most of their products and can fully recommend them.
Payment + Access
Payment is easily done with creditcard or paypal. Instant is access, good.
Script
Works perfectly fine. Recoil control does its job without issues. Controls the recoil very well. Can be adjusted how much it should compensate. Smooth can be also adjusted. Rapid fire also does its intended job. Speed can be adjusted.
Updates
The script was never down for me. They need 1 week or so to add new weapons.
Detection ratio
Didnt get detected as far as i know. I never got banned
Support
Mostly some staff is online. I talked a lot with Salty, he often helps me.
Should you buy?
If you need a legit help or "assistance" for a very cheap price, yes. If you want to rage this might be not the option for you. Its also good for streaming or video recording (streamproof).
