Product review (5 stars): Really good one!
I like this Hygrometer because they shows range of humidity, low and high.  Some people doesn't even know how many percent of humidity is normal and too high.  Keeping proper humidity is very important in a winter time as we use Heater that dries air, then bacteria rise up.  Then people tend to cough or catch cold easily. So using humidifier is very important so as using Hygrometer to see if you get enough humidity. This one is really good, I like it a lot.
