This unit is working great for my intended purpose (measuring shade on hiking trails). I have connected its voltage output to an analog data recorder so I can view the time-varying light intensity levels on my laptop. The unit has been working great for several weekends of hiking, and does correctly identify shade/sun conditions. My only problem is that the switches are not recessed, so the unit got jostled in my backpack and went into a mode where the data resolution became inadequate for my needs, however I bought a switch cover to fix that issue.
