Review: Nicer than expected! - nicer than expected! The picture doesn't do it justice... the display is actually very vivid and pleasing esthetically - which isn't evident from the product's photos. Also note mentioned (perhaps I missed it?) that you can lightly "touch" the upper part (there's sensor there.. not a bottom rather sensor - just gently place your finger there) that toggles between 3 illumination modes - bright, med, and display off. (useful for night time..) Sensitivity wise - seems very accurate, consistant and fast (when on AC power, updates every few seconds). Didn't need to calibrate it as well. It seems accurate out of the box. In the morning when I open all windows wide open, it drops very rapidly to ~400-ish... Seems genuinely responsive to the environment. At night time, without ventilation, it showed around 1500 which is not good. I started ventilation, it dropped to ~800 during the night. You can really get a sense that it's reflecting the actual situation. I can tell the difference when 2 people are sleeping the bedroom vs. one. In short, very nice. Would have been even better if it had WIFI !!! and connected to home assistant. over-all very very nice and useful. Helped me solve my C02 problem. (at first I wasn't ventilating enough, I ramped up the RPM on the inline fan, and it dropped to 800, which is OK, during nighttime).
Review: Great Monitor, Great Price. - Easy set up. Seems to trend with changes and that is what I was looking for. Not to be within a part per million or two, but to see when airing out the room for sleep is needed. We have windows open in winter when needed but not like during the summer, tons of fresh air. Will update if products goes stupid on me.

### ⭐⭐⭐⭐⭐ Accurate and functional. You can't go wrong with this monitor.
*by B***E on December 20, 2025*

This monitor works well. Easy to set up. Uses a high-precision sensor. Comes with a USB cable and also works with batteries. When the USB cable is plugged in, the display stays on continually but can be dimmed or turned off. When unplugged, it reverts to battery power and the display has a timeout. Also displays temperature, humidity, and current time.
