Solid sensor but needs a hub
The sensor is compact and easy to install, but make sure you have a Zigbee-compatible hub. It works well within my setup and the battery life seems excellent so far.

Good performance at a good price
Motion detection is reliable and the device is very discreet. I wish it had additional environmental sensors, but for motion alone, it does the job well.
