The setup was a no-brainer—just press the button and it turns on. It instantly started tracking all the readings, including CO₂, temperature, and formaldehyde. I was actually surprised how quickly it responded when I moved it from one room to another. I’ve only used it for a short while, but already I’ve started checking it before going to bed and in the mornings. It gives me peace of mind knowing the air isn’t full of stuff I can’t see or smell. Also, I like that it gives the humidity reading too—it helps me know when I need to turn on the humidifier.

This thing has a really sharp LED screen, and I like how the numbers are big enough to read from across the room. The color change on the screen helps give a quick look at whether the air is decent or not. So far it seems pretty accurate—I left a candle burning and noticed the VOC number went up. That’s pretty cool. The size is compact enough to move it from room to room. I’ve mainly been using it in my bedroom to make sure it’s safe while I sleep.

I always assumed my indoor air was fine, but this little device has already shown me otherwise. The color screen is super clear, and I like how it changes based on the quality levels—makes it easy to tell when something's off. It tracks everything from carbon dioxide to formaldehyde, and even humidity, which is great since I live in a place that gets pretty dry in the winter. It’s been sitting in my living room, and I’ve already noticed how the CO₂ levels go up when windows are closed too long.

I was skeptical at first, but this thing doesn’t mess around. The CO₂ levels it shows match up with what I’d expect (higher when the room’s crowded, lower with windows open). The formaldehyde detection is what sold me—I’ve got new carpets, and it’s reassuring to see the levels are safe. The screen changes color if something’s wrong, which is handy since I don’t have to stare at numbers all day. Switching to Fahrenheit was a nice touch too.

This little device does way more than I expected. It checks CO₂, formaldehyde, TVOC, temp, and humidity—all at once. The readings update constantly, so you’re not stuck waiting. I like that it shows averages over time, not just instant spikes. The CO₂ sensor seems super precise, and the screen is bright enough to read from across the room.
