Works as expected and detects motion, good quality and easy to install.

Not Bad

The media could not be loaded. It has been working fine for over a year but the sensor range is not good enough. Of the two purchased, one is placed in the courtyard and the other in a hall with access from most of the rooms. This room lacks daylight. It is set to turn on only when someone enters. Both have been working so far without any other issues.

Reliable and durable

I had bought a similar item five years back. It had worked well all these years, and when the need arose for another I had no difficulty in deciding what to buy. This device is accurate, it is customisable and sending direction can be adjusted to a large degree.

Slow asensors

Sensor has not a wide angle. It works only when someone is moving infront of this. The wide angle is less than 30 degrees.Sensor doesn't work if kept over 4 meters range. I have installed it in my gallery of 10 meters but it only works when you are at a distance of around 4 metres or less.Motion sensing is slow. If you run infront of it, it doesn't work. The lights are on after a delay of 2 seconds.

Doesn't work!!

Doesn't work at all!! Don't buy please waste of money. I have put so many sensors but this particular one doesn't work!! Absolutely useless!!!

No Problem.

When I bought the item I was mentally prepared it must be Chiness product for the money I am paying I am not expecting an item studded with diamonds.That besides the point. This is my third buy and is working as I expected. I put it inside the shower Cubical so when we get it the light switches on automatically. It serves for me.Not sure how long it works. For me if it works for 6 months it is ok. Spent 600 so 100 a month. Twice bath four family members so 240 on and offs a month. It is ok. I get my money worth.Thanks.
