We are using this in a classroom, it was easy to setup and is easy to read. With COVID being a huge concern the Laser Egg + Chemical helps us keep a watch on the partical count in the classroom and when the number gets to high we simply open a window or door for some fresh air.

We bought 9 devices for our school and we are very happy about the devices as they keep our children safer. If the PM2.5 go up, we simply open the windows and it drops down quickly. We know that COVID has been shown to travel on other particles, so tracking the PM2.5 was crucial.

Really good service.

Laser Egg was easy to set up and works great. BedBreeZzz advised when I ordered the Laser Egg shipment from the manufacturer would delay my receiving it and kept me informed as to its receipt and shipping date to me. Great customer service.

This little device is wonderful! If you care about the air you breathe or are just curious, you will find this device to be a valuable health monitor. Plus, it has an eight hour battery, so it can be portable to test the air wherever, Room to room or place to place, inside or outside. Would definitely benefit those with COPD or other respiratory issues.

You have to do an outside CO2 calibration before the numbers are correct. I really like the form factor, you can turn off the local display and access the data from Apple Homekit. I am already seeing readings that reflect inside cooking and human presence.

Took a couple of tries before connecting to the internet but these little devices are great. You can clearly see how fast they react when you blow on them! I can now sleep better knowing that my little girl is sleeping in a low CO2 level room!

I’ve had some rudimentary devices to measure pollutants for about the last five years, but they didn’t give me much helpful information. I recently purchased to Laser Eggs + and the difference is remarkable. When we turn on our gas range in the kitchen, the Laser Egg + immediately shows an increase in VOCs. I mean immediately! It gives me a lot of confidence that I now know exactly how my inside air is behaving, and it helps me modify my routines to keep my family safer. These devices are well honed measurement machines. I could not be happier with them. Nicholas J.

In Washington State we have had serious wildfire smoke problems this summer and fall. My egg has been a life saver with identifying air quality in order to plan my outdoor exposure. I am very satisfied!

The CO2 reading was very high and not accurate. I have tested it in many different locations (home, outside, work) and it gave the same high range everywhere. Need to read more on it, might be my house that has bad air. Still returning to test with an other

We have handheld sensors we deploy in our home when there are fires. Are neighbor down the street has an exterior purple air that we use to get real time data.

This sensor sometimes matches our handheld but when it is left in one place it seems to settle down to no particles (it seems to have a minimum at 1mcg/m^3) while the hand held left sitting next to it continues to move around especially at the tenth measurement 6.7-9.8 for instance because air is not static.

I’m at a point where I don’t think it can be trusted and I’m feeling like I wasted $138USD. I thought I’d want the data but the night mode isn’t “off” and thus it’s just as bad as the competitors. I wish I’d spent the extra $60 and bought a purple air indoor unit or saved $60 and bought a temtop m10.

I love the product...it's accurate and informative. I bought it when wildfires created days of smoke in my area. It validated that my air conditioning filter was taking most of the pollutants out of the indoor air. A bit challenging to pair, but finally figured it out...

Setup was pretty easy, just make sure you're connected to a 2.4ghz wifi network.

The device itself looks decent, and fits in well with most home furnishings. Honestly, you probably won't notice it too much until you look for it, which is good - it's non-obtrusive.

I live in a pretty clean air city, and the sensor seems to indicate this quite accurately. Would be curious how it works in somewhere like Beijing or Shanghai. It's a well-designed device that does exactly what it advertises.

Value for money product !

Given the PM2.5 situation in Thailand, this is a godsend.

I took it around with me one day and discovered exactly how different the quality of air is indoor and outdoor.
The reading inside my own house with open windows was 35.
Walking beside the road, it skyrocketed to 80.
In my air-conditioned office, the egg indicated 8 (see photo).

Now I now where I should wear a face mask and where I can just relax and take a deep breath of clean air.
