I've had mixed success with it. I bought what I thought was a way reasonably priced bass about 800 below all the others and it shows up with a ski jumped neck and super high action to compensate that the previous owner of 20 years "never noticed" and didn't believe. Had a Dingwall show up at a reasonable price which had a gremlin I had to chase out (a loose wire) but otherwise nearly flawless aside 2 dings. 2 pedals as well, one that had an issue out of the box that the seller remediated within the week and another pedal that was in new condition. So really only 1 that's a loss for me overall.
As a seller, I think I may go more to Reverb. I had a bass on here FSOT for a while and at a cheaper rate than on Reverb and there was just a ton of aaaaaaaaaaalmost agreeing to a trade. Or just waiting and thinking about it. In the meantime it sold on reverb for more to a stranger without any hassle or back and forth messaging. I imagine if I end up selling the yellow SB-1 I picked up a little while ago I likely will also end up closing the deal on Reverb quickly and with less hassle.

So they're expecting someone to be dumb enough to pay extra for an item from an individual seller who won't allow a return when they can easily buy the same item for $15 less from a retailer who will give them a generous 30-day return period!
