Only used my account for the casino a few times before deciding to exclusively use it for the exchange. Little to none bonuses. Site provides responsible gambling tools. Withdrawals time are fairly consistent (in my case: average of 8 hours), KYC took less than a week and I completed it before using the account, this was many, many years ago and in all this time I never had to contact support, I pay 6.5% of commission on winnings on each market, which is a bit higher than what others pay. Casino simply is not the reason to join Betfair, the reason to join it is the betting exchange, higher odds (even after paying commission on winnings), live betting on horse racing, colossal volumes and an endless selection of markets and many sports and numerous ways to bet/trade as you please, dutching and variable dutching, back to lays, lay to back, building a freebet or taking a loss on a single selection, laying all selections and making a margin on the lays to a guaranteed profit and much more, nearly every imaginable way to bet or trade is possible. Worth mentioning is the third party software (Geekstoy, Marketfeeder, Bet Angel, Gruss, etc) that come in handy for the exchange and increase your possibilities within it: bot/auto/triggered betting, charting, different stake modes and more to make the bettor come ahead. Downside: many unsolved complaints regarding closed accounts, to avoid this simply don't use the casino or the sportsbook, stick to the exchange and everything will be fine. So far, the only operator that deserves 5/5 (to me).
