I purchased the 3day trial after reading a few reviews and finally gave in. I will have to say it has been a great experience so far with a easy to understand interface. I highly recommend using it to up your game and awareness. I wouldn't just go around headshotting everyone as people just leave. Use the esp to understand tactics and common behaviors of enemies and then slowly work your way into being a better player. Read the fairfight FAQ before you engage! Have fun!
