Hello ,
I will like to ask people here what they think about HUD for pokerstars ?

All major HUDs support pokerstars so i suggest trying them out to know which one you would like. I suggest checking the Stickys for recommended HUDs for PS.

For me I suggest DriveHUD because if ever you decide to play on a different site, DH support more sites than most HUDs so you wont have to change your database.
