Like several reviews I saw (following a google search and leading to this site, though the other reviews don't come up now on search! too bad....)
This site seems above-board, explaining how the idea is like "going going gone". But the truth is that there is no point in "bidding" except when the clock ticks down, and it is constantly re-setting, with little to no predictability as to when the required "exactly at zero" push will register. I played against quiet groups only to watch the screen freeze at zero and declare a "new player" winner. I've seen "autobid" tools drive up the bid price and there's no way to know if it's all human beings doing the bidding, and the company makes money on bids, which are fast and furious.
Bad enough that the site is a glorified "eBay themed slot machine" where neither skill nor method can be helpful, and there is never any confidence of it being fair and un-rigged. Worse: Within minutes of "winning" a small beginner prize (more bids!) I learned that (1) there is a $2 "service" charge for the immediate/automated crediting of extra bids, and that this must be paid for separately from the bid account; and (2) after paying from a separate, secure Paypal source, within 2 minutes I received phishing letters from Paypal (which I'd not used at all for any other purchases) saying that I'd successfully bought an electronic item I never heard of, nor bid on. It was a fake, and I didn't follow the link. The next thing I know, however, I'm getting hit by lots of email (actually) from Qbids but sent to variations on my email, not my actual address.
I'm thinking not only is this a racket akin to the "variable reinforcement" addictiveness of slot machines, but it's as or more random, and may be like handing out a blank check to spammers and phishers in addition.
As some of the older reviews *here* warn (and I hope they're still findable!) - I'd definitely avoid this site. It's tempting but ends up stealing hours of time piddling away clicks one cent at a time, bidding against real people, robots, and Lord knows what else. Not only is it totally unlike the consumer-oriented eBay site, offering protections for buyers (and identifying the seller!) but there are usually only one or two "bait" items (iPads and an occasional laptop) mixed in with all the packages of bids - easy to win and hook one into more profitable bidding on impossible to win items.
