Product review (5 stars): works great - fairly quick and accurate
This humidty / temp meter is a nice unit.  It comes in a black case, has great instructions, and comes with a 9 volt battery.  It is quite easy to use; just turn it on and hold the tip where you want to measure the temp and humidity.  It does take a minute or so for the temp readings to adjust when you going from one extreme to another, so the reading isn't "instant."  But it is close, and the readings were consistent with other digital devices I own.  This is a great professional tool for AC workers, home inspectors, or just an average handyman who would like to add this tool to the collection.  Overall highly recommended!
