Some say it's detected and its only half of the truth. You can play on servers wich are PB disabled at the moment and you won't get caught.
Also ppl say that it only works half of the time..
You can fix this issue with this: When in game press ` and write "render.drawfps 1" after this ESP works all the time..
I'm posting this coz i get a lot of ppl saying that there is no working free hack.. when everything is in this forum just you need to find it. I personaly tested this esp. Actualy i played with this hack from lvl 1 to lvl 18 now.. Just play on PB - off servers, remember that! I hope no one will ask for working ESP hack no more.
