Product review (5 stars): Great lightweight portable weather unit
I've been using my Ambient Weather WM-3 for a about a month prior to writing this review. My primary use for the device is for weather reading while camping, hunting and fishing.

The unit lightweight and compact enough to easily fit in a pocket or small storage pouch.  It's made from plastic but doesnt feel cheap. The unit comes with a lanyard and a little protective carrying pouch as well as easy to follow instructions.

The operation of the unit is very easy, turn it on and start taking measurements.  It does allow you to change your units of measure and also allows you to record your minimum, maximum and average wind speeds as well as give you reading for the temperature and the humidity.  The unit also has a backlight that automatically illuminates the screen for about 10 seconds.  It has a auto-off so if you forget to shut the unit off it will turn off automatically and not drain the battery.

The readings seem very accurate as I compared them to my profession weather station at home before taking the WM-3 out into the field.

For hunting and fishing I wish I had one with barometric pressure readings, but for $29 it is a great device and think it will give me years of good service.  I would definitely recommend this device to someone looking for a compact portable weather station at a great price.
