Product review (1 stars): M
This instrument never worked right out of the box. Neither the thermometer or the hygrometer changed after I removed it from the box. After 72 hours the temp remained on 85 even though our home was at 73. The hygrometer seemed stuck on 45%, the value that it read when I unpackaged it. Even if it worked, the numerals are hard to read, and the cris-crossed needles are confusing and strange. I returned this item.
