I used to love betfair but use it very rarely these days. Seems to have got worse over the last year (no longer in the BMR Green List). Most concerning and the main reason players bet with them was the great odds - this is not the case anymore. The ability to lay, means betfair is a vital cog, but I do feel that they have really lost momentum, and should have been the true sport betting giant, always offering the fairest odds on every event - not the case. The fixed odds product and push towards casino, games and poker shows which way they are heading.
