Product review (5 stars): Basic, reasonably accurate, well designed screen.
Superb basic tools. It should be obvious that, at this price, these are not laboratory instruments. However, my two agree with each other, and their temp readings agree with my other home thermometer. It may be luck, but it is good enough that I just ordered two more. I like having the humidity and temp, having the high/low, and that these don't have a clock or calendar or other irrelevant gadget. Simple and adequate.
