Product review (1 stars): Hopeless-takes forever to stabilize.
Pointless. It takes forever to stabilize--it automatically turns off before it ever does. If i want to wait that long, I'm better off with a simple analog Hygrometer for less than half the price, that at least doesn't constantly jump values by 5.00% or more every second. Its pointless that it pretends to offer accuracy to .01%. After 5min it was still bouncing around with values within a range of 2%.
