Don’t know to buy this brand or not
Spent money to buy trashy product trusting the brand. Out of the box product didn’t work. I hope the company have a quality check counter to trust the product they are assembling then trash they are assembling and wasting consumer money. No phone number on the box on the instructions to contact them. There company moto should be buy it if don’t work trash it Bec you will not be able to contact us anyway. So there is a connection diagram on the sensor that wire in wire out which is printed wrong when reveresed in and out it finally worked.

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.
