Product review (1 stars): Temperature accuracy is poor
The temperature accuracy on this is +/- 2 degrees F, which is not accurate enough to make it very useful as an indicator of room temperature comfort. There's a big difference in comfort in a room at 72 degrees versus a room that's 74 degrees, for example. And what's the point of reporting temperatures in tenths of a degree, when the accuracy is only to plus or minus 2 degrees? It is pointless and even deceptive.

I blame myself for not reading the specs more carefully before ordering.
