The cheat remains undetected and totally safe. It totally depends on how you are playing the game. IF YOU HAVE 999 FOV and 0 Sensitivity - Then get banned. Use a little sense and try to play like a real player with the cheat. Try to record your own gameplay and see if you are suspicious and correct that mistake. And cheating is only possible for serious players - if you aren't serious you'll keep getting banned. I've been playing all these seasons with 4.7 KD and still didn't get banned.
So my recommendation is to use the cheat if you are serious about playing safe. And yeah have a good #WWCD
