Satoshilabs (short: SL) is a faucet site with a very attractive twist. I’ll explain later. The site is absolutely free to use, it doesn’t require any investment (only time and patience). It doesn’t even allow you to invest, so anything you earn is pure profit.
The site is SSL secured, which is an indication for professionalism. SL is easy to navigate and doesn’t hinder you with annoying popups or popunders. Only in rare occasions you’ll receive one of those, but hey: they have to generate income in order to pay their members.
