Does what it says, fire it up for instant readings.

Absolutely wonderful addition to my workshop and helps me to know when I should wear a dust mask and when to leave the workshop for a cup of tea! I looked at cheaper models from other sources and did a lot of research (a lot), and this is a well-trusted brand with a good history of making devices of this kind, giving me confidence in the product. You need to calibrate it from the box which is no effort at all and it has been great ever since. i t has a wide range of readings and p[resent some nice graphical information which for me (an engineer) is really appreciated and useful :) No issues at all and very pleased with it

Good quality, good value for your money. And easy to use

I have no way to check the calibration, but it seems to work well. We all have allergies in our house, and we leave it running most of the time. Its silent, and the charge last about 18 hours of use. You often feel like your a ghost buster wandering around the house to see whats reading what. I do laser engraving on a cheap chinese thing and didnt realise how much crap is put into the air. It also settled an argument between myself and the wife about what was worse for allergies, the cat lost, the dog isnt anywhere near as bad for airborn particles. 😀

I needed to check the air quality in my home due to COPD. It works well and reminded me to out the window vents

great value for money seems very accurate and easy to use.

Bought because I was worried about formaldehyde and a lot cheaper than calling someone in. All OK on that front. The particle sensor is an added bonus ... try it after hoovering 😀

Works well but very expensive for what it is would have bought it if I had known
