I wouldnt have used it a few months ago but since my dicovery (through this forum ) of betfair i need it ........when i first started i just laid every fav that come along and lost the lot ...i think evert fav in australia got up that weekend lol so i settled down and got selective got all my losses back withdrew em and ive still 600 in the pot ....i dont play big but it adds when your not losing often
