95% of the amazon listed items are garbage.
I’ve discovered over time ...
Reading reviews, the five-star reviews are almost 100% good and posted within the last few weeks / month.
the one-star reviews span more like the last year or two. Bad reviews showing the products have failed badly.
Another big discovery in the one-star reviews are how many manufacturers deny warranty claims if you bought it on amazon !!
Another amazon failure is a shopper’s ability to find out WHERE IS THE ITEM MADE ? Where do the ingredients come from ? Much is hidden online from amazon.
the one-star reviews span more like the last year or two. Bad reviews showing the products have failed badly.
You should always sort reviews by "Most recent". "Top reviews" are selected by an algorithm that pushes "helpful votes" that can be easily manipulated, among other things. It's also not uncommon for quality to dive once an item starts selling.
I love the honest reviews that say “This is the best product ever. It does what it is supposed to do. I recommend this product.”
