Dunno how to use evadeee propely

[mohammedXD]

I always see people saying on bol shoutbox and nulled's also that the evadeee is the best evade script, but the scripts doesn't evade propely every time... sometimes it works when something is coming from FOW or from the bush, but lots of time, on laning phase/team fights i get grabbed by someone,do i need any custom config? what to use to make it work propely?
