The Nonin Achieve does the measurements well but if you want to use it in dark environments it has a serious problem. The back light only works sometimes.
Amazon replace mine, but the 2nd unit behaves the same. The device has an ambient light sensor. If it senses low light the back light should turn on. I think the problem is that the sensor is very sensitive to infrared. If the ambient temperature is over about 75 degrees, the light never turns on.
At about 80 deg I tried the unit in a dark area -- no light. I put the Nonin in the refrigerator for a few minutes. After chilling, the back light works for a few minutes until it warms to room temp again.
So it seems they have a design flaw. Don't buy it if you need to use it in the dark.
