You don’t see a problem with users being completely unable to predict with any accuracy how good the quality of what they’re buying is?
Amazon reviews are a pretty bad indicator of quality. You often need to make educated gueses about whether the reviewer knows what they're talking about, whether their standards are the same as yours, whether they're a shill (which is very common on off-brand items), whether the review actually reflects the product and isn't referring to the shipping or customer servie experience, etc.
