Amazon Prime has become a prime (haha) example of how capitalism is failing. It's not the best price, it's not faster anymore, it's not good quality and you can't trust anybody.
Amazon is being flooded with the cheapest of the cheapest stuff from China and alike. Either with ripoffs of well-known products or just 25 items which look the same but are from different "brands". Finding "good stuff" for a topic you don't know about is getting harder and harder.
Those items also aren't cheap though, I've found better quality items at a local store for nearly the same price. Lazyness just made me buy it quickly on Amazon, because I thought it was the easiest (as in "cheapest + fastest") way.
You also don't whether those items are good after all. Reviews are 50/50 mixed with people who were paid by the manufacturer for a positive review or by competitors who want to make a product look bad. My personal favorite for the last time probably was a "is this any good?" question where somebody responded with "I've made you a quick video" and posted a hiqh quality, advertisement video. These reviews and answers are so blatantly fake but there's no way to report them. Amazon doesn't care after all, too. So, the trust is gone.
Ok, but we'll receive the items quick and be able to judge them by ourselves then? No. Prime regularly takes 3-5 working days for me now. I don't know what thei problems is, but does anybody remember the times when you received a month of Prime for free if your item was not delivered on time? That's long gone.
Prime, at this point, is just "free shipping", nothing more.
