almost all faucets are waste of time, but you can try mexiciantarget' faucets, they are just perfect, if you will be smarter and try hard for several week, you can earn 200-300 k satoshi from them every day. i think its best way to earn free satoshis without risk of lost any.
Can you share with us some of those faucets (or at least send PM). I am interested to check them out.
