Just a couple of days ago I needed to buy another iphone USB-lightning cable. If you want to get a sense of just how broken Amazon reviews are, try searching for one of these. It's a nightmare minefield of 4.7+ rated products that have these highly dubious 5 star ratings, but with a telltale sizeable chunk of recent 1 star reviews.[1] So I ended up having to also check various meta-review sites or other product review sites just to to buy a stupid cable. For certain product categories, reviews have become mostly noise.
[1] I tend to discount really effusive, highly detailed 5 star reviews for basically mundane products. "This ethernet cable was both highly attractive and yet lighter than others I've bought in the past. I plugged it in and it immediately started working! I was amazed!"
