Unit works reliable and is easy to read. Connection via App is smooth and leaves no questions. I'd wish that there where more customizable warning limits for CO&CO2 like a "silent alert" for increased levels and the posibility to stop an alert-sound when noticed (at least for non-critical levels)
Unit is also a bit heavy but therefore it seems rugged. Battery drains quickly (lasts appx. 2 days) so have a powerbank handy when you travel.

⭐⭐⭐⭐⭐Highly recommend for campers & RV travelers!
I’m a big outdoor‑travel enthusiast. I backed this device on Kickstarter back in 2024 and have been using it ever since.

This monitor literally saved my life! Once I felt drowsy after driving and decided to sleep inside my RV. I was half‑asleep when both the unit itself and my phone went off with loud urgent alarms. I immediately realized I was facing carbon‑monoxide poisoning risk. I snapped awake, opened all windows and doors, and got outside right away.
We later found the generator exhaust pipe was broken and detached, letting toxic fumes flood into the RV cabin. Without this device’s timely alert, the outcome could have been fatal.

✅Pros:

- Durable aluminum‑alloy body, great resistance against bumps for outdoor use
- Responsive touch‑screen with clean, well‑designed UI
- Real‑time readings on phone App; supports reviewing history logs and exporting data files
- Comprehensive sensors: CO, CO₂, UV index, heat index, temperature & humidity
- Built‑in emergency light on the back; fully customizable alarm thresholds
- Carbon Monoxide uses UL‑listed 10‑year lifespan electrochemical sensor; CO₂ uses infrared sensor. All certification documents were publicly available on Kickstarter, which I have verified. My real‑life emergency experience proves how reliable its sensors are.

❌Cons:
Battery life only lasts about 2‑3 days. It would be perfect if battery runtime could be improved in future versions.

Absolutely must‑have safety gear for enclosed outdoor spaces. Highly suggested for RV and camping use!

Easy to use nice display and plenty of useful features. The Bluetooth connection and portable design are my favorite parts.

I have used it for camping and hiking trips. It is compact rechargeable and gives me useful environmental information wherever I go.

Feels well made and the screen is bright and readable. I would have liked a slightly more detailed quick start guide.

The device is useful by itself but being able to connect it to my phone makes checking the data much more convenient.

CO CO2 UV temperature and humidity all in one unit. This replaced several gadgets I used to bring on trips.

Small portable and easy to pack. I like being able to check conditions around our campsite on one screen.

There are quite a few readings on the screen so it takes a little getting used to. Once you learn the layout it is very useful.

I use it when camping and spending time outdoors. The combination of gas monitoring and environmental readings is very practical.

Lightweight and rechargeable which makes it much more convenient than carrying extra batteries. Great for outdoor trips.

I wanted something portable for checking air conditions inside our camper. The CO and CO2 readings are exactly what I was looking for.

Really impressed by how many readings this small device provides. It does not take up much room in my backpack.

The monitor itself works great. Bluetooth setup took me a few minutes the first time but the app has been convenient since then.

The screen looks great and the touchscreen is responsive. Everything is displayed clearly without feeling complicated.

We keep it with our camping and road trip gear. Rechargeable portable and easy to check at a glance.

I originally wanted a CO monitor but having CO2 temperature humidity and UV readings makes this much more useful.

Works well and feels sturdy. It took me a little time to get familiar with all the readings but after that it was easy to use.

Small enough to bring in my backpack and the display is easy to read. I especially like the temperature humidity and UV information.

Bought this for our RV and it has been a great addition. CO and CO2 monitoring in one portable device gives us extra peace of mind.

The Bluetooth app is really useful. I can check the readings on my phone without constantly looking at the monitor.

Took this on a weekend camping trip and liked being able to check CO and CO2 levels on one compact device. Easy to carry and simple to read.
