Works
Works as good as much higher sensors. User Interface is a little hard to use.

Wildly inaccurate
Picture taken around 300' above sea level where O2 content is 20.9%. Shame the accuracy is so poor. It's UI, utility and function are otherwise good.

O2 Percentage is only 35%
It cannot read more than 35% O2 purity; so it is limited on what it can read or where it can be used.

Product failed after a couple of uses
After a short while 3rd or 4th use. Got descalibrated. Evenfollowing manual procedures to try calibrate again, it won't. Alarms keep beeping. A waste of time and money.

Easy to use and it does work.
I tested it by exhaling on it and the reading went down immediately. I blew oxygen on the sensor using a bottle of Boost Oxygen and it shot right up to 25%. The only thing I wish for is if it can read upwards of 50%. The limit at 25% is too low if you are to use this to test oxygen concentrators.

Bad Unit No Support after outside of Amazon return window.
Item arrived. Appeared to work ok. Didn't get to really use it for 1 full year and when I did the only thing that worked was the LED Light. Contacted their support who had me try a couple of things which I did and they didn't work so I restated my original problem that missed the first time. They never responded back. It appeared the unit had an electronic problem at the LED screen would light but that's all it would do... not boot up or screen information. I also learned that most unit sensor under $100 only last about a year. If you only need a unit for less that a year... then this might work... but don't count on any support, Don't waist you money if you need it for more than a few months. I wound up paying $275 for one that will last at least 3 years... and comes with real support.
