As of June 2017, worthless. No longer recognized by ebay
7 Aug 2017
Worked until June 2017, then ebay blocked their authorized access. Any access of ebay results in a request to change your password, and no bids will work. eSnipe was notified of this with multiple bid losses, and chose to ignore my complaints as well as those of others.
If you send esnipe money, you're giving it away. Customer service is nonexistent and they have no intention of giving refunds now that their service is defunct. Ebay is unrelated to them and offers no help. Stay far away from esnipe.
