I buy a lot of unbranded stuff. Or, rather, brands I don’t recognise and aren’t well-known. In my experience branded goods are often made in the same factories, by the same staff, to the same specifications and are frequently the same products.
Brands tend to establish themselves by building a reputation for quality and customer service. They then trade on that to build a reputation as they double down on marketing and raising their profile. Once this is done there is a tendency to become complacent or, frequently, be bought out and the easiest way to increase profitability is to cut costs. This is often done by cutting back on customer care and the product itself. The things that made the brand worth having in the first place.
Whenever I see a brand being promoted I think of a familiar logo emblazoned on a thin box with lightweight plastic goods inside. And then, if I am in the market for a similar product, I look at the name no one knows, costs less and has better packaging, responsive support and actual physical heft.
