I often select Amazon warehouse or refurbished items (don't recall precise wording) and from experience, the quality often is surprisingly shabby, or put differently, that category of merchendise is substantially under-discounted. Metal supports bent, components missing, protective packaging conspicuously breached or smashed. I found this article insightful as it tends to explain the processes that lead to such items being listed as if they are undamaged, conforming and nearly-new. At this point I assume products distributed in that channel are significantly defective albeit probably functional with some effort.
