I've been using the software about 6 months now, I think, and although it's not perfect, it is the best tool I've found to help me save time while doing sweepstakes! So far through Ninja I have won:
Nail Polish from Cosmopolitan
Cars activity book from Disney
Ooh La Lash Mascara from Woman's Day
Elayda 6 Piece skin Care set from RealBeauty
3 NCLA Nail Polishes from SheKnows.com
Elemental Herbology Weekend Kit
Sink Mat from Woman's Day
and I think there was a CD in there somewhere.. hehe =)
Thanks Sweepstakes Ninja... here's to hoping the next win will be bigger and better =)
