Customers say
Customers find the motion detector easy to use and appreciate its small size and wide input voltage range. The functionality and build quality receive mixed reviews, with some finding it works well while others report poor quality control. The sensitivity and sensor range also get mixed feedback, with several customers noting it’s not very sensitive. The product lacks a wiring diagram, which customers consider a negative aspect.
