Sounds like you are trying to refute the majority of negative reviews to justify using the service. Personally, I'd stay away just based on what you have said. Maybe find a friend that will sell it for you for a cut if you don't want to bother with it?
I sold mine on craigslist to the first responder and #2 was very disappointed. But I had thoroughly researched its value, cleaned it up REALLY well, staged it, and took a couple of dozen of pictures that I posted along with a detailed history of its usage. And most importantly, I priced it fairly. Didn't ask any dealers, but I'm pretty confident I got way more than they would have given me. So that would leave lots of room for a friend (or even someone else) to earn some easy money.
