Accurate, Reliable, and Easy to Use!
I’ve been using the Temptop M10+ for a while now, and I’m really impressed with how well it performs. The accuracy of the readings is spot on—I’ve compared it against other monitors and it’s consistently reliable, which gives me confidence in the data I’m seeing.The battery life is fantastic. I can run it for long stretches without worrying about constant recharging, which makes it super convenient whether I’m using it at home, in the office, or while traveling.I also love the display—it’s clear, bright, and easy to read at a glance. The layout is intuitive, so I can quickly see all the important information without fumbling through menus.Overall, this device has exceeded my expectations. If you’re looking for a dependable air quality monitor that combines accuracy, long battery life, and an excellent display, the Temptop M10+ is a great choice!

Good product
We’ve had this for about 6 months and it has been working great. Temp and humidity are same as some different meters that I have, but I have no way to validate the air quality measurements. Battery lasts plenty long – I think I’ve only charged it twice. I like the eInk/paper style display.

Great purchase overall
This thing works really well, any time I open my IPA bucket, I look up to check it’s functionality, it usually always reads the VOC’s pets quick making it’s accuracy verifiable. I think it was well worth my safety and that of my families, great value for my money. The battery last extremely long, I still haven’t charged it since purchasing (about a month now) and looks pretty professional near my printing station.

App is so-so but device is good
The app doesn’t do a whole lot feature-wise, but the device on its own is great. Lasts an eternity on a full charge!EDIT: I noticed that if you set it to constantly rotate through the different measurements, the battery drains much, much more quickly. I just leave it on CO2 PPM and it can go weeks without a recharge. If I want to see other measurements I either manually switch on the device itself, or check the app.

A merciful/very slow air quality meter
The marketing for this product discribes itself as “meticulous” and “real time” to imply it is fast to respond and doesn’t miss anything. I have sat infront of a fire for close to 30 minutes now and it’s still saying the air is clean. It seems to turn on once every hour takes a few samples then turns back off missing everything between. It’s rather useless for everything but long term averages in a static environment. Also find the claim of “comprehensive” alarm to be funny. It has 1 toggle for the alarm, on or off. That’s it, it in fact could not be simpler. You can’t even change what reading the alarm goes off because of. Rather disappointing for 130$. I will be returning it most likely. Much better is available for slightly more and the same quality is available for lessOne thing I can say is the co2 sensor seems real and isn’t a virtual one. It’s difficult to see how it responds to tests because it doesn’t respond to anything for nearly a hour

Great air quality monitor
Great air quality monitor. I love that it can last a whole month with a single battery charge. I also like that through the Temptop app you can access it’s recorded metrics.

Wildy inaccurate VOC readings
I’ve been using this for about a month to measure air quality in my home. I wouldn’t recommend it if you need VOC readings.Pros:- Good battery life- Nice display- Thermometer works well.- App integration works well.Cons:- Wildly inaccurate VOC readings. I’m using it in an enclosed space with very little airflow. The readings have a variance of over 200. Very disappointing as measuring VOC was the main reason I purchased this.I wouldn’t bother getting this unless you want a very fancy thermometer.

This is an excellent, accurate unit that helped me associate my afternoon headaches and dizziness to high CO2 levels in the room. However the iOS app is horrible. The login screen elements overlap each other, making interaction difficult. Yes, you can view historical readings, but it’s very cumbersome. If you’re interested in this unit, assume you won’t use the app.
