Usability / Functionality
All the games that "PerfectAim" provides uses a usb and I can say it's the quickest way ever. I've been using this on my main account for a month now and I can say it's the safest cheat out there.
Features
https://perfectaim.io/cheats/rainbow-6-siege/ You can find all the features there. It has everything that you can ever imagine in having in R6. Aimbot/ESP probably the only 2 you need mostly lol. Wish the gadget esp worked :(
Security
Been using my main account for 1 month semi raging called out a couple of times and my account is still fine. It's also never been detected. Used it on an alt account and it has like a 5kd ratio lol, yes I kinda raged. But no manual banned as well. Nobody wanted to rank since they're scared of me being banned and them losing elo. But little do they know I'm using "PerfectAim" 
Conclusion
It's the best cheat out there. Fun to closet cheat to not get called out and or semi rage like me and still not get called a closet cheater most of the time due to high lv lol. But you still gotta know the game knowledge to not get called out most of the time. I've spent probably 40+hrs in the pass month to get plat 2 and getting any higher isn't easy even with cheats xd. But I can say this is worth the time to grind for invite and probably the cheapest cheat out there as well. So good luck everyone and I hope you enjoyed my review. - Love Riven <3
