Review on Maxxima 3 Grounded Multi Outlet Adapter Wall Plug - Expand to 3 Outlets with Outlet Extender Wall Tap - Pack of 4 by Paul Walters

Great product. I was a bit skeptical when I saw that there is no screw to attach this adapter to an existing outlet. However, my skepticism was dispelled after I installed and tested one of these. The top grounding prong rotates slightly down and the bottom grounding prong rotates slightly up (parts that fit into an existing outlet) keeping this wall outlet adapter securely in place. This is a wonderful design that works well. I recommend this product.
