i claim 20 sts  

I was paid right now by RainBTC, directly to FaucetHub.io, thank you! I liked this one, I rarely got 10 satoshis per claim (the minimum reward), 40-50 satoshis came very often for me.

Very good faucet very good design I really like the bad thing is that it takes a little time to make the payment to its users

Why minimum withdraw and not instantly withdraw?

To increase the site income you can add short-links and set it as optional to your users. Like, if they choose to view the short-link you increase the claimed reward on that turn by 30% let's say... Pop-ups are an option too, but I see some people complaining about it...
