Product review (4 stars): Not too bad for the price.
I got this direct from China. The temperature is very accurate - within 1 or 2 degrees. I have nothing to compare the hygrometer. Mine never goes below 20%. The highest it's gone is 72%. I'm pretty sure the humidity was more than 72%. It's good enough for me though. At least I know if it's very humid or very dry in the room and roughly to what degree. I can see it drop when I turn on the A/C. I gave it 4 stars considering the quality for the price. It's been working for about 2 years now. Oh BTW, the clock isn't very accurate after a long period of time, but that's not what I bought this for. If you want something accurate, spend more money.
