I am sure this topic has been beaten to death, but I have a gift card balance at amazon and wondering what your guys recommendations would be for a hygrometer you can get on Amazon? I've been using the same cheap digital hygrometer that can't be calibrated for a while now that is 8 points off (I make sure the deviation stays the same frequently) and I'm sick of it being off. Any recommendations? I see they have both the circular and rectangular Xikars... any to look for? Any to stay away from? Thanks fellas.
