Product review (1 stars): 1 out of 3 are bad? Really Reminds me of Star Trek series line ...
If I could go lower on review I would.
Buy three and see if you change your mind on high praise
Two working one not (so far)
Your fooling yourself and so are they.
Humidity Reading is problem which is why I bought it !
My thermostat can give me temperature.
No return policy means they know they have a problem.
1 out of 3 are bad ? Really
Reminds me of Star Trek series line
Fool me once shame on you fool me twice shame on me!

Save your 10 bucks or fool yourself into thinking its accurate.
