I have noticed that a lot of sellers, mainly based in Asia, are selling privately. This means that when a buyer leaves feedback other buyers cannot see if there has been negative feedback left on the item they are interested in. I suggest that anyone leaving negative feedback should put a brief item description, as diplayed by the seller, to warn others that the product is not worth purchasing, and then a one or two word comment eg. DON'T BUY! That way other buyers can read that the item they were thinking about buying could be a dud.
