Absolutely fantastic, the graph with the two sensors (based on different technologies!) reporting every peak and valley in perfect synchronization almost made me cry. Beautiful. Then again the values reported are not the same, one of them seems to be more sensitive and goes higher/lower all the time, so I would still not know which sensor to get and how much to trust the data. I guess if the price is as equal as they state (~$20) then the more sensitive one would be "safer" if trying to avoid too high CO2 levels.
