Sleek design and functional

Looks great on the shelf. The data history in the app helps me understand ventilation patterns in my apartment. Highly recommend for anyone concerned about air quality.

Good value for money

Does exactly what it says. The alarm feature is loud enough to hear from the next room. Battery life isn't applicable since it's plugged in, but the USB-C port is convenient.

Great accuracy, simple setup

Connected to my Wi-Fi in minutes. The temperature and humidity readings match my other professional sensors closely. Only wish the cable was a bit longer.

Perfect for my home office

I noticed I was getting sleepy during work hours, and this device confirmed my CO2 levels were spiking. The alerts are timely, and the E-ink display is very easy to read without glare.

Improved my sleep quality

Started opening windows based on the CO2 readings before bed. I feel much more rested in the morning. The integration with smart home systems is a nice bonus.

Essential for greenhouse monitoring

Using this in my indoor greenhouse to monitor plant health. The remote monitoring feature via the app is fantastic, allowing me to check conditions even when I'm away.
