Product review (5 stars): simple and nice, cheap and very useful
I have been looking for Humidity/Temperature for long long time

Believe it or not, they usually goes between 40-50 range in retail

This one is very good price and it does its job

it doesnt have light up for screen but I didn't expect that much

back of this unit is not flat so it is not easy to stick to the wall

but it is small enough to place anywhere

I bought 2 of these and compare those 2 after few minute later out of box

they both come out same number for temp and humidity

so at least no calibration difference

it is small and simple and do its job

will buy again if needed
