Good unit
I’ve had three of these for about 10 years. Two are still working after all this time and the third one failed when the bulb burned out and caused a momentary short circuit. The sensor failed a fraction of a second after the bulb. Shame but stuff sometimes happens. Replaced the failed unit with a spare and all is still well.
Another reviewer mentioned that the range is insufficient. I’ve found that while the units do respond to a 360 degree circle, they do not respond equally in all directions. The unit responds excellently in two opposite directions and poorly in between. The manufacturer must know this because the center terminal is spring loaded and makes electrical contact about a half turn before the sensor screws tight into the socket. Thus, you can unscrew the unit by about a half turn and still have it work. I’ve taken a few days and slowly unscrewed the sensor from the ceiling socket a few degrees at a time until the most sensative direction faces my single point of entry. Works much better that way. Doing similarly might help some folks.
Update (9/6/2010): This item is currently on sale here for the lowest price I’ve seen.

Works well
I bought four of them. So far, they seem to work well. They do not work with CFLs well, but are fine with incandescent bulbs.

Wonderfully convenient
This is an amazing product. I love it! If they were less expensive, I’d buy five or six. I have one in my basement, where the bulbs are old-fashioned screw-in-to-turn-on types (not pull chains). Yes, I could rewire the basement, but in the meantime, this is the perfect choice. Like many motion-sensing devices, this socket doesn’t work with a flourescent bulb; package instructions say to use it only with incandescent bulb. It also can’t be used in an enclosed fixture, only a bare-bulb fixture. But for closets, garages, pantries, basements, etc., it’s perfect.
