they arent a sponsor but BetAllSports knows management very well and he can prolly make a call to them if u needed help with something in ur account.
beyond that. I dont use them mainly cuz no big bonuses.
but from my previous experiences.. they have dime line baseball which is nice.. also they payout decent time frames and take cc as deposits as well as the normal ones.. they have poker (but i tried it and software was too slow for me).
