These site will gradually fill up - quite quickly initially but it will slow down over time - until you make a claim.
so even you came back after 4 weeks later. that's ok! it still add the amount. that's very suitable those busy people that can't claim every 5 min.
they also no need sign up. just use your bitcoin address to login. they will remember your amount you claim.
you can click Payout link any time, any amount. they will sent to FaucetBox right away. Simple and easy just like their Get Your Bitcoin or World Of Bitcoin. no need afraid waitting a week then lost your balance.
