UPDATE
I already tried the chair, the 1 day free trial and finally bought myself, so many feature in the chair, none like others (I thing this is the only feature rich chair for rivals i have tried till now) , you can try the config shared in forum or create your own, as long as you don't RAGE, or get to high accuracy, like perfectly track spiderman while swing or something like that, you good to go and safe.
People said it never safe to use silent aim..?, or magic bullet..? its totally safe if you know how to not to be too obvious, and using reasonable FOV (i am only use silent aim, its my favorite). The thing that will get you ban its not the chair, but others report you after watch your replay and seeing you have a perfect aim ,track, or impossible hit angel, so be wise with your setting/config, read the forum before using it, never try and error on comp match.
Overall rating from me 9/10
additional feature suggestions : Fake mouse movement would be better.
