Product review (2 stars): Item in package not as labeled
While this additional unit works great for remote temperature, the actual unit only measures temperature and not humidity.  The package (sealed clam shell) is labeled temperature and humidity, however the item included inside is only a temperature unit (actual device does not say hygro on the front).

I expect this is a manufacturer packaging error - but as I could use a temperature only unit, and with cost of return shipping, not worth the hassle to return.
