for me its super rewards as they dont just take sms people can get ingame extras by completing surveys, use credit cards and phone which is all good but downside is some players have issues with completing some of there surveys or being credited for them, but they dont get issues when they pay by phone, credit card..just seems to be the free offers that players have issues being paid...and the other down side is how much you get out of it ..say you sell a 50bucks pack you proberly end up with around 30bucks of it but then again its donations you wouldnt have other wise and i think all companies that offer these types of services do take a big chunk.
others are proberly just as good or maybe better just sr is what i use
