Module works well - although I wish it had a bit more templates/customization available on the design.
Bug in IE
Would have given this a Good rating except I found an bug in IE (tried in both IE8 & IE9). The auction details are cached for repeat visits when using IE. Works in Firefox and updates accordingly so I have cache settings fine.
For an auction extension having stale data isn't a good thing since it makes the visitor think there is more time available on the auction (and lower price) than what is actually represented. I don't want a potential bidder thinking that have days left instead of hours.
