Product review (1 stars): We have a few others and they register humidity super accurate! Buyer beware
You get what you pay for!  This thing is junk as far as a hygrometer goes.  The humidity levels are so wayyyyyyyyyy off!  We have a few others and they register humidity super accurate!  Buyer beware!  I am now 2 days off from the return window , darn-it!  DO NOT BUY THIS!!!!!
