About 3 years ago, I sold lots of domains there in the $25 to $200 range, and had sell rates of maybe 40% with the first or second listing. It went downhill, and I haven't tried much since. A year or so ago, on a free listing day, I listed about 30 and sold none.
When I did list there, I actually got better response listing domains in the category of the use of the name rather than under domain names. For example, something like camerasales.com sold better when listed under cameras where photographers frequent, but not so well under domain names. Doing this is more likely to get a retail buyer rather than a wholesale reseller. As long as the title has "domain name", buyers will find it even if not listed under domains.
