Product review (5 stars): Easy to use with a easy to read display
Disclosure: I received the WM-3 free of charge for evaluation and review. I am not compensated other than receiving the product free.

The first thing I see is it comes in a easy open box. No heavy duty scissors needed. In the box is the meter, manual, case, and a lanyard.

The meter is well made and sturdy. The fan is well protected and checking with Ambient Weather support, it is water resistant, (not water proof don't submerge) and can be used in the rain. I still would not want to get it soaked in rain.

The battery was already installed and no contact protector to remove, it worked straight out of the box. I have checked the wind, temp, and humidity with a friends calibrated hand held who works at the weather service, and out of the box it was well within accuracy specs of the WM-3. The wind and temp was the same as his and humidity was 1% lower than his. I also checked with a liquid thermometer as the manual says with same result, and a friends weather station for wind temp and humidity with similar results.

The meter is easy to use with a easy to read display. Just turn it on and hold it in the wind and use the set button to step through the readings.

Overall this is accurate, comes with a easy to read manual, and is easy to use.
I will be taking this with me any time I will be going outdoors.
