Better than expected
KP✓ Verified Purchase•September 2, 2018
I mean, for the price of $86 -5% and same day shipping you can't even get any kind of O2 sensor cell. Even the cheapest one from Ali will be ~$50 +s/h and take a month to get here.
This unit appears and performs exactly as described. Inside it's made much better than I expected. They use a regular and recent pyroelectric O2 cell (made in June 2017), Analog Devices ADC, ST MCU. The boards are designed and made well enough for a proper (not the cheapest) device.
I expect it to last longer than usual 1.5 years, because in my situation it will be measuring low O2 levels and only on-demand.
Just calibrate it once in awhile with fresh air as described in user manual, which is good by the way, and it will last a few years. The sensor itself is replaceable.
What it lacks is external 5V power input and more readable display. Other than that it's a 5!
Will add some pics of the internals if someone wants it.

Fantastic

Not entirely sure what is going on with the negative reviews. Works exactly as desired, used and left in a fish house all winter. The pilot light will go out on my Mr. Buddy heater when the O2 hits about 17% on the meter, at that point a cigarette lighter stops working.
Other reviews didn't read the chinenglish instructions. Needs calibration before use.

Check the instructions for calibration procedure. Once you do the calibration in normal clear air it works really well. Will update if I have any issues.
pretty accurate when new
Alan✓ Verified Purchase•January 14, 2018
Low quality, pretty accurate when new, after a year measurements were off by 50%. No way to adjust. If you purchase buy the extended warranty.
Dangerously unreliable.

Dangerous unreliable. Sometimes it would work, other times the reading would drift erratically in open air.
