Negative Positive
Title: Better in theory...
Review: I got this to use with my night light, but, apparently, this needs bright and direct sunlight on the sensor to work properly. Even though my room gets plenty of sunlight, the light shadow cast by the neighboring cabinet was enough to tell the photocell that it was dark. In addition, my night light stands up, casting another shadow on the cell (and the polarized plug makes reorienting it impossible). End result was that the night light was on all the time. To top it off, this unit dims the light bulb, hiding behind the claim that doing so extends bulb life. Using an automatic timer instead of this works much better.
