And that's just the immediately visible problems. In some product categories it's difficult to find a single product where the description doesn't outright lie about features or quality, and the only way to tell is the price.
Louis Rossmann recently tested some of the highest-rated fuses sold on Amazon. It took over 8A to blow a 2A fuse.
By now I only order there if I can't find a more local alternative, the only remaining area where Amazon is still ahead (or rather, not behind) are delivery times.
