Product review (1 stars): Absolute junk. Do not bother to buy. Does not worth effort or time.
Have not have such a junk for a long time.

Bought one thermometer - out of the box it always showed -40 and 99% humidity (how it could be?). Returned and get the second one. This one never bother to connect to the sensor and do not show outdoor temperature at all. All troubleshoot instructions are useless.

It use to be that you get what you paid for, but now things changed - you paid for the Chinese junk no matter what you are buying and how much you are paying.

However what you can expect from the biggest junk manufacturing country?

My old thermometers (regular one) worked well for more than 20 years and showed temperature quite accurate +-1 degree. Will look for the same one. (By the way, it is still much cheaper than this piece of work).
