Air Quality Monitor, Formaldehyde Detector, Temperature & Humidity Meter, Pollution Tester, Sensor; Detect PM2.5/PM10/PM1.0 Micron Dust, Test Indoor TVOC Volatile Organic Compound Gas1

I like the look & feel of the device. However, I can't give it a better rating because of the fact that they do not clearlyprovide a way to communicate with them. I can't validate the reading are or meet the standards.

How about a way to turn off the ear piercing chime and the ability to change from Celsius to Fahrenheit. That would be great.

This monitor has great potential and the readings were very good. However, the device is cheaply made and parts were breaking.Straight out of the package the screen cover popped off. A short time later the USB port became unattached and fell into the device.The vendor was nice and refunded everything. I would buy this device again if they built it sturdier. I also wish this model would come with an app-driven WiFi component and with a port to attach the device to the Internet. Of all the models I researched, this one was one of the best. I really wanted to keep it.

The unit worked right out of the box and seemed to have accurate readings. I wish that there were better instructions on how to convert the unit to display Fahrenheit and not just Celsius. Have gone through the manual and settings several times. Would like to keep it...but sending it back!

WORKED WITH OUT ANY ISSUES SO FAR ?,

I ordered the black one and it did not come with a power cord. Lame!
