I've had this device since December of 2015. Plan on replacing batteries every 2 months. My old Radio Shack that lasted 22 years had the batteries replaced every 2-3 years. I would look for some other brand.
1 1/2 years later outdoor temperature and humidity are off by 15 points.  Really garbage buy something else.
