Plenty of sellers that will take pictures from all angles except mysteriously omit one obvious angle - like say showing the lid on a playstation 1.
You can almost guarantee there will be an issue, usually a huge scratch.
Also quite a few sellers listing things as brand new, but if you actually have the item yourself to compare you can tell it's been used as the packaging is missing certain small labels. Recently I've seen a few controllers put back in the original boxes, but wear marks visible or the cords tangled, in which case it's more Like New, not brand new.
