Product review (2 stars): Short life span
Bought this 2 1/2 years ago and it seemed to display accurate temperature and humidity readings for the first year. After that it started to go through batteries at an alarming rate and has become prone to flickering where the numbers on the screen show all 8's or flash on and off. It does this when the batteries are new or old, and it happens a lot when I pick up or even touch the unit. I will replace this with a different brand that has higher reliability ratings.
