Hi Kat,
It's true that all sniping services are at the mercy of eBay to some degree, but we have been working hard on our service to achieve the best results. Over the past few months we've made significant progress on "Ebay Requires Account Verification" as well as many other areas. I hope you've been seeing much better results in your sniping these past several weeks.
That said, the past two weeks and especially the past few days have been particularly difficult on the eBay front. They've had a number of system issues which have affected buyers and sellers in several ways. This can also be seen on independent sites such as Down Detector. This resulted in some lost snipes last week but we've put additional safeguards in place and have managed to work around the issues since then.
Regards,
Todd
