works great
It displays the expected percentage of oxygen while outside. Blowing on it lowers the percentage, as does spraying it directly with a stream of argon. I can't calibrate it any more accurately than that but it will at least detect displacement of oxygen to some extent and seems to be relatively sensitive.

Accurate, simple and fast response
It has a very rapid and accurate response time. I am experimenting with co2 and o2 relative atmospheric pollution levels primarily with and testing for plants ability to absorb and neutralise airborne toxins.Very happy with it as it's simple to use and very precise.

Serves it's bought purpose.
Considering I have nothing to compare it to I can't exactly say if it's the best. But it work for the purpose I bought it for. I have no complaints for this product.
