## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great unit for indoor air measurements
  

*by S***R on Reviewed in the United States on January 2, 2021*

We are doing a home remodeling project and I wanted to monitor the air quality in my bedroom. That’s the only “safe” space in my house at this point. The unit is working flawlessly. Love it! The set up was a little challenging. But I figured it out quickly.You can setup text alerts for  monitored particular levels. If the levels are too high, I open the windows or turn on an exhaust fan to let in fresh air.

### ⭐ 







  
  
    This is not compatible with the WS-0900-IP
  

*by S***F on Reviewed in the United States on February 2, 2021*

The product description is out of date and this sensor will not work alongside the WS-0900-IP.In order for this sensor to work with the ObserverIP module you have to upgrade the firmware to the latest version (4.6.1).  This firmware version is not compatible with the WS-0900-IP and causes the outdoor sensors to no longer communicate.I give it a 1 star not because of an issue with the product itself but because Ambienweather's description is misleading and I am sick of being forced to upgrade an otherwise perfectly functioning device.  If you can't backport sensor drivers then don't advertise your support for them.

### ⭐⭐⭐⭐⭐ 







  
  
    using to monitor indoor levels with different filtering
  

*by O***C on Reviewed in the United States on August 5, 2020*

Monitor is super sensitive to sensing the p levels I'm trying powered electrostatic and several brands of filters in all price ranges. no significant data yet due to me not getting together.
