Product review (1 stars): This product is junk!
This is an awful product! I have had it for less than a month and it stopped working. The top half of the display is gone. I changed batteries and everything. It has not been dropped or even touched since I got it. I bought it for my toddlers room because he has terrible
Asthma and I need to control his sleep environment. I was so excited about this gauge. I put it high on a shelf so he couldn't touch it and it stopped working. Its crap!
