WONT BUY AGAIN.
Gave this product the benefit of the doubt after my first order, but Ive had two sets stop working on me. Only 1 out of the 4 actually work. Two of them, the displays just stopped working and one of them has a permanent 20% humidity reading.

The return window seems small, Ive been unable to return.
