If you like it, use their paid service. They use Rainbowtables at the backend, which is an open source hash cracking tool available with gigs of hashvalues in a table. To avoid all that, just use this service. How effective? Well, make a hash value and test it out for yourself. :)
Oh, hashing is no longer secure, by the way, try encrpyting the transport then hashing the secret values, that should be the best.
