500 sahoshi every 1440 minutes is pretty low rewards and very heavy to loading pages because your faucet still have several annoying ads and i guess you must remove it if you want to get more visitor because majority here don't like faucets with annoying ads
500 satoshi every 1440 minutes can are a medium rate, but the really rate is this
500 (1.5%), 300 (2%), 150 (97.4%) satoshi every 1440 minutes.
only 1,5 % possibility to win 500 , with all this bad advertising and pop up, for me is only waste time
