Only lasted 2 and a half years
Purchased the ARS100 in April 2019 for $120. Worked reliably for about 2 and a quarter years and then started to have high variances in readings every few seconds. Appears that maybe the sensor looses its ability to sense the correct O2 in the air. Retested several times with same outcome. Was kept indoors and in clean environment for the whole usage lifetime.
