I purchased this after looking carefully at the Norelco website and the Amazon pictures.1. My razor says to order the "HQ8".2. The picture on the package shows a complete head set, heads and frame.The package arrived (with picure of heads and frame), but the package only shows the heads.The heads do not fit my razer. There are two little "ears" at on the perimeter of each head, but my razor does not have indentions for the two little ears.If I could easily get a full refund, I'd do it right away, but I suspect it is too much busywork to get one.Be careful before buying!
