Update: Changing my rating from 3 stars to 5 stars all across the board!!!
On the fence with this one. Product either gets a star or loses a star after a month of tinkering. The device randomly turns itself on and off with no clear evidence of motion in and around the area. I confirmed that the 4sec, 1m & 2m settings were working as they should and they did. By the way, the 4sec interval is way too short to serve any purpose! 15 & 30sec intervals would be better. Came in here to read the reviews and the Nay sayers gave me an idea to tinker with. Will be blocking out what the sensors are able to see into a small rectangle using duct tape. I really want this to work because I really HATE having to tell Alexa to turn the lamp off only to get sassy lip service from her. Will check back later. *** UPDATE *** Instructions need a bit more details. After 3 days of tinkering and hair pulling, if you find that the Westek device seems to turn itself on and off randomly, read instructions below before returning... 1. Plug in the light you wish to control with the Westek device, manually turn it off and then unplug it. 2. Set the Westek device to 1 minute and plug it in (w/out anything plugged to it), let it do its "knock, knock" thing and wait until finished (about 5 seconds). - You can change the timing but for setup purposes 1 min. 3. Plug the light into the Westek devices outlet, & wait maybe 5 sec. Then manually turn the light on. 4. Walk away from the sensor and in one minute the light should turn off. Walk over to the sensor and it should turn on. After that, it should not randomly turn on or off and should work as intended. ... show more

Work great, with 2 pointers
I’ve had four of these. I use them on my 220 gallon fish tank. They were great! Two things I’ve discovered: #1 It seems that if you pair them with and appliance that uses too little electricity, they won’t work. I thought mine had failed on a circuit with one small LED light. I simply added another light to the same circuit, and it started working again. #2 vibration throws them off. I had it on top of a fish tank lid that had minor vibration. I put the sensor on a nearby dresser, and the problem was fixed. Hope this information is helpful! Enjoy ... show more

Sweet motion detection
Starting with what I didn't like - the controls for the timer are on the back of the plug component. This means that when you plug it in and decide you want the power to stay on for 10 minutes rather than 20 (for example) you have to unplug it to make that change. Not a huge deal, but depending on WHERE you are installing this it can be a pain to have to unplug to adjust. Why not put it on the front of the plug? At least then you can make the adjustment easily. Nice length in the cord between the sensor and the plug location. Not a flimsy cord, so it feels solid and like it will last a long time. The sensor works like a champ and has no delay that is measurable in my opinion. In our use case it actually was to good because it picked up movement in another room that required me to block a part of the sensor so it wouldn't go off unless movement is only in the area desired. I wish they had a distance control also, but can't complain for the price. I think this is a great value and it work wonderfully for us. ... show more

Stopped Working After 3 Years
Worked perfectly for 3 years--and then the motion sensor stopped working. Now it just keeps the lights on 24/7.

Frequently fails to power off
When set to 4-seconds, any reasonable motion will cause this switch to turn on the power (yea!) and then turn it right back off a second later (boo!). You can do jumping jacks in front of it; the switch will flash on and off for as long as you jump. If you were hoping to build a motion-detector activated disco dance studio, this is the setting/switch for you. Long time settings are more problematic. When first plugged into the wall the unit will rapidly flash on and off 4 or 5 times, and then settle into watching for motion in a powered-off mode. Strange, but OK. Now make a motion that it can see and yes, the power comes on! Leave the room, wait for the set time to pass, and you can observe from a distance that the power will go off. Sweet! But if you bring your wife into the room to demonstrate your brilliance (power on!), exit the room, and then have her observe the switch from a distance, she will observe that it never shuts off. As will you, all alone, at the end of the hall, after your divorce. As was suggested in another review, I switched everything off, unplugged my load (a multi-outlet extension cord connected to a 5-watt light and a 50-watt stereo amp), unplugged the motion switch from the room's wall plug, and then reinstalled everything precisely according to the instructions that were included on a tiny square of paper that came with the switch, being sure to follow each step in the order given. In my case the switch wouldn't shut off, not even a single time. Perversely, I tried following the instructions in reverse order (except for step 1, setting the time setting, which physically has to precede step 2, plugging the until into the wall) and I got the switch to work as advertised for a couple of days, until it reverted to always on. Dead-on-arrival would have been preferable. ... show more

So far it's doing exactly what I wanted
I got this device to use with my wife's low-wattage space heater she has under her desk in our home office. She's frequently forgetting to turn it off when she leaves the room and I happen to come back into the room hours (sometimes the next day) later to find it running all that time. She even uses it in the summer sometimes so not only is that wasting power but also fighting the AC. Her heater is infrared and only uses 500W max on its highest setting (250W on how); that is far below the 1400W rating of this plug. Setup was quick and easy. I just placed the sensor off to the side of her desk in the included, weighted base holder, set the off delay time (I used 5 minutes), and plugged it on. It has been working perfectly thus far. The great thing about this one vs. others I was considering is that it will keep the power on continuously as long as there is motion in the area, then turns off after the delay time if there's no motion. I've seen a number of people say that these go bad after a while and start staying on for no reason, but thus far ours is working perfectly. I will update if that changes. So far we are 100% happy with this. It was affordable and solves a problem; now I don't have to worry about the heater being left on and likely this thing will pay for itself rather quickly in savings on our power bill. ... show more

Worked well right out of the box
I used this to light up the stairs where a wall outlet exists. You can select the "on" time with a rotary switch on the back of the plug in part (the instructions say "off" time). The sensor head is aimed to where you want to pick up motion, which is an IR sensor (picks up heat motion). To indicate power, there is a red LED on the plug in housing. There is a relay that makes a quiet snap sound when it turns on, so you might consider than if in a bedroom. In areas of the country where the power quality is bad with line surges, the relay should last way longer than an electronic switch (Thyristor based typically in these kind of switches). Note that this unit is ETL safety certified which is just like UL. I was very happy to find that in the product reviews - why isn't this in the spec on Amazon? Big selling point. UL/ETL is very important for fire and shock safety and is often not found in products from Asia. I am very happy with this. ... show more
