I've bought close to $100.00 worth of bids on this web site and have won O. This is in spite of manually placing my bids extremely strategically. They give one a free spin per day which is a nice feature. However it usually ends up being only 1 free bid.
I personally wouldn't give this site any of my money. I've noticed the bidbutlers usually win. Being no limit placed on bidbutlers I think it's possible either for the very same people to win all of the items and/or the business to make it so they are the ones keeping the items to be used time and time again.
I wouldn't recommend this site. I've reviewed almost every single penny auction site on the net. 1 out of 10. I would give them an 1.
