Product review (3 stars): Works well but no instructions
Great thermometer that works well indoors and out but the very brief instructions do not give enough information on how to calibrate things like local humidity, and other advanced features which are not intuitive.  It is a generic version of a name brand which had the same complaints about the instructions. Overall it worked great with the basic setup in wet Western Washington, just had to accept humidity was uncalibrared and therefore relative.
