It seems pretty accurate. The South Coast Air Quality Management District tested a bunch of consumer devices against a $30,000 professional device. I was deciding between the IQAir and Laser Egg 2+, which both did well according to their tests http://www.aqmd.gov/aq-spec/evaluations/field. I got the Laser Egg 2+ the other day. It's really enlightening to see how it spikes when we cook dinner or lunch on the gas stove.

Does the Laser Egg 2+ monitor CO2? Looking at the kaiterra product page [1] I don't see it
