Probably better than most survey programs
I've been using e-rewards for several years, and overall it is a good program. There are numerous rewards options (travel rewards seem to be a good value), I've never had a problem receiving rewards, and the surveys generally work as advertised. As others mention, there can be issues with surveys suddenly ending after many inputs claiming the taker does not qualify, some surveys require too much time for the reward, but you can pass on it beforehand. Due to the site consistently being active and never having an issue with redemption, I think it's as good as one can realistically expect.
