Save a lot. Still in use after 6 months. Best for someone easy to forget to turn off lights.
When it arrived, I plugged it into our walk through laundry room (between garage and house), plugged in a little light in the corner on the counter, and it works like a charm. Then I saw this little sucker. Great function, well worth the money. I can't tell you how much money I spent on motion switches to replace wall switches. But I kept running into issues like 3-way wiring, florescent lighting, etc. I intend to buy more for other places that I don't spend a lot of time but where I often need light while there but forget to turn off.
The success rate of the device was about 5%. I placed it in my garage in the hopes that it would activate a light as I entered in the dark. I would not recommend this product. After owning this sensor for 3 years I have finally decided to unplug and recycle the unit. The sensor never really worked the way it was intended. This left me in the dark 95% of the time fumbling around with my keys.
They are setup so that the fan goes on for roughly 10 minutes every time I walk by the sensor. I am using two of the sensors to run fans in my living room and kitchen. They have worked well for this purpose over the last couple of months.
While in another room, I often hear the fan cut off when the unit timed out, but it would immediately start back up. Both units seem to time out OK, but only cut off approx 10% of the time. I like the definitive time settings on my replacements rather than the variable dial timer on these units.PROSNot much to recommend, since neither of mine worked correctlyCONSWould like a longer sensing range (possibly adjustable)Temperature operating range is way to narrow.Variable timer located on back of unit-have to unplug to change settingsTimer not marked-timer setting is guesswork (not that bad a problem) I purchased two of these units and neither works. I have a 16" floor fan plugged into the unit so it would turn on when I walked in the room and circulate air while in the room (had the timer set on max time). I'm guessing 10% of the time, it would actually stay off when it timed out.I would also liked to have had more range on the sensor, but that's a toss-up depending on your intended application-if you want it to turn on only when relatively close, fine-if you want it to sense motion at longer distances (my application), it was a bit lacking.Sent an e-mail to the manufacturer with no reply-was going to return for replacement, but I've since found a similar unit at my local Harbor Freight that seems to work, so I'm sending 'em back to the maker for a refund (per their warranty).The unit I'm replacing these with has more range and a switch on the side to select 5, 10, or 30 minutes.
