Mary, I don;t remember which ones were advertised. If they were by MGW, I have them, and they are very nice. They install with special fasteners and have a gasket that keeps them from sitting directly on the paint of your sill, and can be removed in minutes. I think George has them listed on the "new products" area of the VCA boards. If they are the ones that cover the sill with an aluminum sheet and a Viper stick-on logo, I would only say that they may look nice, but are installed with tape...getting them back off would be a real problem.
