Product review (5 stars): Accurate and very easy to use
Don't be fooled by this device's small size.  An easy to use accurate meter (<1% temperature-difference/<0.5% wind-difference  between this and a "professional" station at a friends' house).  Instructions are concise and easy to follow, but the device is simple enough to figure without the manual.  Wind-speed/thermometer is easy to change between English and metric units.  Large LCD readout easy to read even for those of us "aging-amateur" meteorologists.  5 out of 5 stars.
