    When it worked it was great
  

*by S***Y on Reviewed in the United States on August 17, 2018*

We got this product and it worked great.  We  packed it away for 10 months when we have fire season and need to check AQI.  Wonderful for a week and then the batteries stopped working.  Changed them out multiple times with multiple brands and no go so it only would work if plugged in.  Then, 2 weeks later the entire thing stopped working and will only read an AQI 250 regardless of where it is even if we know that the AQI is different.  I have contacted the company.  We will see what they will do about it.  I hope they honor their product

*by G***R on Reviewed in the United States on May 4, 2018*

Worked great for about 2 months of occasional use in a home wood shop. Then it began reading consistently 60-80 high.  For my purposes, its not worth paying a lab to calibrate it every few months to make it work.  Paid $45 dollars shipping to return it to the factory (in Asia) for repair.  Repair was free.  Process took 6 weeks.  Have had the device for 2 months since repair and it works good.

Worked great then stopped reading air quality after a few months. Reached out to manufacturer and zero response after multiple emails.
