Product review (5 stars): Accurate factory calibration and easy setup
I purchased this product to remotely monitor my tower cigar humidor. My initial concern was the sensor's factory calibration, as there is no way to manually calibrate the sensor. I have purchased many factory calibrated hygrometers only to find they were off by as much as 5%. I tested this unit in a calibration bag and found it to be perfectly calibrated. Now I can rest assured I have an accurate reading for my precious cigars. BTW, if anyone is having issues setting up the gateway, use the downloadable gateway tool on the support page of La Crosse Alerts. The tools works perfectly too. Thanks Amazon for a fast delivery and thank you La Crosse for an inexpensive and accurate product.
