## Customer Reviews

### ⭐⭐⭐⭐ Works
*by R***Y on March 19, 2023*

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

### ⭐⭐ Wildly inaccurate
*by E***0 on April 12, 2023*

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%
*by L***. on September 7, 2021*

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