Product review (5 stars): Ambient Weather WM-3 Handheld Weather Meter
Awesome device! The readings are very close to what my Davis Vantage Vue weather station reads. I really like the built-in backlight it has. It comes on for ten seconds or you can over-ride it and keep it on. It comes with a lanyard and carrying case. To change the battery located on the back there is a door you can open with your fingers. No tools required to change it. Great meter and great size as well. Maybe about two inches wide and seven inches long. Only wish the screen was a little bigger but it's easy enough to read.  I received this product free of charge in exchange for a review. This is a great product!!
