Product review (5 stars): An extremely accurate hygrometer.
I have used 3 different brands of digital hygrometers in almost 5 years.  This is hands down the best hygrometer I've owned.  It is well worth the money if controlling humidity is essential to you.  It has an easy to read display and is built extremely well.  I use it for maintaining my cigars and trust it 100%.  Every time I open my humidor the hygrometer reads 65% humidity, the same as my Cigarmony cigar beads.
