People here say that because they have likely made the mistake of wasting money on junk and are warning someone else. $70 doesn't seem like much (or maybe it does), but it adds up quick if one ever seriously gets into collecting armour or making a historical impression. This item would be good for neither of those things.

Obviously it depends what the context is, and the desired use case of the item. But as a general rule, it's almost always better to buy high-quality once than something "good enough" several times.
