I like how bright they will adjust to (even though I use them at the dimmest setting) and the fact that they are off when I am trying to sleep and NOT walking around the bedroom. Probably saves a little electricity by not being on all of the time in other rooms.Great adjustable brightness night light that comes on by sensor or stays on all night. Very small and compact.Like some reviewers have mentioned, the nightlight stays on in some rooms. In one bathroom, it goes off and on as expected. In another, the natural lighting is too dim, and the nightlight stays on all the time. That said, I'm guessing it's seasonal. When summer arrives, I'm sure it'll be a different story, as more light comes into the room in question. However, if they'd just add an on-off switch, when that would be preferred over a light sensor, it would solve the dimly lit room issue. I'm not sure why they just didn't do that in the first place.They last for a long time after the trigger, and they work way better for night time bathroom breaks because of this.I have them installed in my home entryway, bedroom hallway and dinning area. Light brightness can be changed. Purchase these.this product works as intended. I think the motion detection does take a second to detect motion. but apart from that I have been very happy with the purchase. 2 light intensities and 30 sec timer once it detects motion. just what I needed.Comes with two nite lights- one worked perfectly while the other just stays on the entire time ( the switches do nothing for the bad one, you plug it in even if it’s in the off position it just stays on). The other working one is perfect, wish both of them worked as well.We walk through a small laundry room to go out the garage and these provide plenty of light. They turn on and off as needed so no worries about leaving the light on.
