Temperature is right on, humidity is iffy
I purchased a few of these and have had one I'd been using for the last 5 years or so--they're easy to read and accurate with temperature, but, on lining them all up next to each other, to make sure they were all measuring the same, I realized that the humidity varied with each unit. It was usually within 5%, but it was annoying to realize they were all different. I even tried them in different rooms and different spots and they were all consistently off every time when it came to reading the humidity--I have no idea which one of them was actually accurate, but they were close enough for me to be okay with it, and the temps were always the same, so that helped a lot.
