Generally, for smaller purchases, it boils down to things like didn't like it. Also, And I've seen this with yard equipment a lot, folks will buy it, perform a job with it, and then return it after the job is over. I always haunt the big box return sections in lawn and garden. I did get bit once by a refurb ryobi blower, slowly wound down to where it wouldn't run, nothing to do to counter that, but it was only like 25 bucks and I figured I got 25 bucks of use out if it anyway. Didn't stand up to the 5.56 real well at the end, though.
