Living in a wet environment, The closed while in use covers are benefical if installed properly. The old gray covers did their job providing they were never opened, hence the stamped message on them, "Not waterproof when used". I have replaced several water damages recepts from open / broken covers that were FUBAR'ed. I have replace ones that were not damaged and rarey used and the device was in mint condition despite being located in a driving rain for 20 plus years. They CWIU covers can be easily damaged though if the recept is an are of high traffic areas. I use them alot up here and several have been busted. I did get a couple of the low profile sample covers that some linked to a while back. It is good concept but I am a little concern with the tension from the flexible portion cover will do to the cord over time and the look of them seem "odd looking" when cocked when something is plugged into them.
