I used MaxiBidder for more than a year and had a lot of success with it, and gave it a good rating the last time I reviewed it. But I also experienced lost bids. That's not usually the developer's fault, since eBay keeps changing the way their site works and necessitating tweaks to the sniping software, no matter which sniper app you use.

But the developer of MaxiBidder is often slow to respond to these changes, and his attitude toward his customers is unprofessional. Often complaints or questions go unanswered for days, not acceptable for commercial or shareware apps.

There are better options available. I now use JBidWatcher, a great snipe program that is Java-based, cross-platform, speedy, reliable, and handles multi-snipes (where you can set up 2 or more snipes as a group and it will bid on each of them until it wins one, then stop bidding on the others). JBidWatcher has a lot more features than MaxiBidder, and it's free.
