Be cautious, because most of the faucets have flow of money but are not secure, else its a good deal. The only distracting part could be low payout of faucets.
It is true. This free scrips have not security. Faucet like this can be easly hacked or botted and you can lost everything in few hours..
I would say few hours not required just few minutes are enough. never keep high balance in your wallet.
