This is definitely the best GPT site I have ever used. It gives generous payouts per survey and you get bonus money for every five payout requests made. I've had bad experiences with other GPT sites in the past, whether that be no payouts, rude support, etc., but GG2U has never failed to impress me in all those areas. The support is super friendly and quick to reply, and the organization is very transparent about how they work and what it takes to get paid. The only thing I can really complain about here is that the payouts aren't instant, but it takes only a day at most for them to happen and hardly detracts from my positive experience.
Thank you GG2U!
