These are pretty great! Obviously, the key selling point is the ease of install, and it is indeed pretty clever. A monkey with a screwdriver could do it in about 30 seconds (excepting the outlet centering issue, which I'll get to). But the design goes beyond the clever means of connecting to power. Overall, it is very slick, clean, and looks exactly like any other faceplate on your wall (which it should!). The light sensor IS visible, but much less so than I expected. Once you're standing a few feet away, you don't even notice it. A friend of mine put a few of these in as well, and I didn't even notice until I was standing close enough to the panel to set it off.The light quality is also great! I generally like things dark at night, and have never particularly needed nightlights. I installed this in the kitchen, and was happy to find that it was just bright enough to make it easy to grab a glass of water, but also didn't make it appear as if the room was permanently lit up - the quality of the light keeps it from reflecting around and illuminating the whole room, and rather just adds enough visibility to the area to allow you to see things. Aesthetically the appearance of the three LEDs glowing downwards is very appealing, too.
