Works for about a year then stop working. Warranty is useless.
I have purchased 10s of these devices for my house. The sensor works well for about a year or so and then stop working. With me it keeps the light on without any motion. The lights is switched off for a second and then opens again even if there is no one. I have replaced the sensor almost 3 times. Warranty is for 2 years, but when i contacted the company they asked me to record a video of fault and then courier the device to them and then they will check and send a replacement after a month. The courier cost was more than 200 and I found it to be more of a hassle than to buy a new one.

BUY IT HONEST REVIEW .
good product tested it absolute value for money pretty basic to install if u know little about electricals using a 4 sensor setup on my duplex staircase with rgb strip will update pictures once finishing phase is complete , one suggestion i had to use masking tape to limit detection . just remember red wire provides current output or red is live wire for ur appliance .
