Product review (5 stars): Impressed, Vey Accurate Product
Well, this is the 3rd Temp/Humidity Meter I have purchased.  The first 2 were returned as the readings were way off (especially humidity).  This one, the Extech 445815 was a surprise for me. I use this meter for my Tobacco Fermentation Box, and lease to say, the readings must be accurate for the process to work.  I have yet to find a "wireless" meter work so accurately as this "wired" one.  I required either a "wireless" or a "wired probe" for my fermentation box as to reduce the opening/closing of the box to read the inside temp/humidity.  This one does it!  After running the "salt-test", the readings were perfect at 75%.  The temperature readings were accurate as well.  I'd recommend this product if you're in need of accurate humidity and temperature readings.
