Query: Not like they used to be

I've bought several of these over the years, but these were not like the ones that I'd seen in stores. They're made of a lighter, cheaper plastic that feels like it's going to break, and the microfiber cloth is terrible quality. Make sure you hold out for the real thing; these are an overpriced knock-off that don't work half as well as the original
