Product review (1 stars): stay away of this product.
Product arrived in non-working order because of the improperly set screen inside, I had to open and figure out how to connect the screen. It had been clearly, improperly assembled.  Arrives without instructions. After fixing the screen and let it sit for a day, the thermometer is accurate, but the humidity is off by a lot (30-40%).  There seems to be no way to adjust it.

I would not recommend this product.
