This is a very cute nightlight - not overly bright, but that's why I purchased it based on other reviewers saying it was slightly dim. You can turn the castle slightly to either side so it isn't "flush" with the wall which may come in handy for some. I think you have to put it in a very bright room to activate the sensor because where ours is located, the light is on day and night - it just doesn't get bright enough in the current location. I don't necessarily mind, we've had that issue with other dawn-to-dusk nightlights. Being LED, it shouldn't have a huge impact on the overall life of the bulb. Overall, really happy about this purchase, especially since they didn't have anything this cute at the store!
