I have lost several auctions on E-bay recently using StealthBid. The items went for less than my maximum bid listed with Stealthbid. When attempting to get a reason it just says unable to bid. There is no way to contact a real person. I have complained several times through their on-line feedback and even asked for my money back. No response. It is absolutely useless, even worse than that because it causes you to lose auctions you would have won simply by bidding through e-bay for free. Don't fall for this scam company.
