Works nearly every time for me!

The bid sniper is a fantastic tool! You place your highest bid with 5 seconds (or less!) in the auction and both ebay and other bidders are hard pressed to respond fast enough. It gives you a greater measure of self discipline, too, because you don’t have time to allow your best bid to slide even higher. I find the tool very useful.
