When doing our online auction, we found this site easy to set up. With the necessary information even if we are not a US based organization.
We also received positive feedback from those who decided to bid on our items, as it for the most was self explanatory how to go about registering as both a bidder but also bidding.
Our bidder also likes the function that let them know if someone over bid their high bid.
We liked the fact that the company reached out to each winning bidder and let them know that they had the winning bid at the end of the auction.
