good motion sensor.
have been using it since 2 weeks and the product is performing well... The motion sensor range is good and and the light switches off as the per the desired time. Also the option of moving the sensor up and down and right and left is very useful. I am using it on the staircase...

Works as described
Lux adjustments works, time can be tuned from 15 sec on-word. Distance/lux is bit difficult to adjust but default full should work for most of the requirements. Lets see how long it will last. my last similar one ordered from aliexpress worked for almost 6 years. value for money.
