Excellent value
I'm using with Smartthings and it is working well so far. Connection to the hub was quick and painless. The sensor is responsive and performing as expected. Edit: Had 3 of these for coming up on 18 months and still on the original batteries, so excellent battery life.

Perfect product.
I use Frient sensors, both the pro and the standards excellent products. They work great. Delivery wasn't as swift as norma though.

Annoying flashing light
I use this motion sensor with Home Assistant using Zigbee, using it to detect when things have been left on in an unattended room, such as the iron. It's easy to setup and use, but there is no way of turning off the annoying light in the middle, which flashes regularly. I would have bought more for use in other rooms were it not for that light, which I find seriously distracting.

Good Value But Can Be Slow To Respond And Don't Rely On The Adhesive Pads
I bought this to work with a Samsung Smarthings system which it does natively and much more cost-effectively than a Samsung original unit (I have some of those too). Good points: It uses regular AAA batteries so they shouldn't need changing very often and will be cheap to replace, and it comes with both a corner mount and a flat surface stand. It contains an LED which illuminates briefly when motion is sensed. Not so good: As it uses regular batteries it's quite a bit larger than a sensor using button cells. It's also a bit slower to report motion than the Samsung models. Looking at the Smartthings app, the Samsung sensors are almost instant whereas the Frient once took over 30 seconds to respond. I stuck the unit's corner bracket to the clean, flat wall using the supplied adhesive pads and it seems to hold fine, then a couple of days later the unit went offline while I was out. When I came back I found it in pieces on the floor with the batteries spilled out. I put it back together and it's been fine since (so I guess it's quite well made), but don't trust the adhesive pads to hold. Use the screws supplied if you want to wall mount it. All in all, I'm glad I bought it and it's a useful addition to the Smartthings ecosystem. It doesn't report the temperature like others, but for the price I'm happy.

It detects motion?
This has to be quite simply the WORST addition I have made to my smart home. As for the basics: Packaging was very basic, the box included the sensor and a base to sit it on (inc fittings). The device itself isn't made of the most sturdy plastic, felt like I was going to break it when attempting to turn on the battery. In use: I needed a sensor in my garage to turn on when motion was detected, rather than a typical door trigger. I paired this device to Samsung SmartThings Hub, which was effortless to be honest. Furthermore, I had no problems pairing these devices up and then installing the sensor where I wanted it to go. Problems quickly arisen when in use. I had this sensor to link up to two Philips Hue bulbs in the garage, and an automation setup for the light to turn on as soon as motion was sensed. I then had it setup for a five-minute delay, upon which is no motion was sensed after that time, then it would turn the lights off. Simple. Sadly when putting this into action, it was a huge fail in terms of the sensor. The delay from when walking into a room, and then for events to trigger, was terrible. I could walk into the garage, go to the other end, stand for a second and then walk back before it triggered (you can see a little green light on the front flash when motion is sensed). There is no ability to increase sensitivity, it just is what it is. I did remove the automation & replaced it with a much simpler one, with a bulb that was really close to the hub, walk in, light on...nothing else. Still, this motion sensor's performance was terrible. I do have AEOTEC motion sensors in other non-main areas of the home, and they work great with Smarthings, so I was really disappointed to see how this device performed. Quite surprising too, as this brand have lots of smart home products that work on Zigbee. I gave up in the end, and found stock of the Philips Hue motion sensors. Decided to pick up some of them instead, and they work flawlessly. I really can't recommend this product at all, and I would be concerned about any of the brand's other offerings.

Great value for money.
Great sensor. Bought it after not being able to get the Smartthings motion sensor any longer. Paired easily with my Smartthings hub, and now controls my bathroom light automatically.

Not compatible with Zigbee Gateways
It installs very easily if using a Zigbee enabled Echo. However, if using SmartLife with a Zigbee gateway, forget it. Also, when using with Alexa, it will not work with any “detects no Motion”. The way I got around it was to set up an “on motion detection” with light on - wait 1 minute - light off. Thought I would try it though as other models only last 12 months and then you need to buy another one. Thus negating any money saved through energy management. I shall re-review again after 12 months

Great!
I bought this to add to my Home Assistant set up using Zigbee2MQTT and they're pretty great. They're bigger that others as they take two AA batteries but their sensitivity seems to be pretty good and the 'cool off' period between motion detection is around 25 seconds. Some other cheaper motion sensors can be up to 2 minutes... There's no temperature or light level detection but I bought this for motion, so no big deal. Overall a great device for motion detection.
