Youre right. “Cordless handheld vacuum” is a descriptor and not “the name of a product”.
In fact, on the Alienware website, the product is called ‘Alienware 34" Curved QD-OLED Gaming Monitor - AW3423DWF’
Alienware 34" curved QD-OLED gaming monitor sounds a LOT like exactly what you described. And then the SKU is tacked on to the end because they sell multiple various models of of 34" curved QD-OLED gaming monitors, and people are going to want to get the right one, so they make it prominent.
The official product page is an actual monitor name, and postfixed with the encoding to help differentiate similar models. So you’re right, but also, “AW3423DWF is a terrible name” is wrong, because AW3423DWF isn’t the product name, it’s just how people identify it, because there are so many similar monitors out there.
