Product review (5 stars): Works well and is easy to read
The humidity here in Virginia can make a big difference in outside comfort.  This small monitor offers several benefits as I plan my day.  The outside temperature and humidity shows in big numbers that can easily be read from across the room.  The inside numbers give me a point of reference.  It's easy to find units that show inside temperature and even both in and out, but few show humidity and that is almost as important here.

This unit is relatively small so I have it sitting on a shelf where I can see it easily.  The outside sensor can be hung on a hook in a protected location where it's easy to access for battery changes.  It is weather resistant, but not waterproof so I hang in on a porch.  You always have to change both sets of batteries at once and always put in the sensor batteries first.  I've made the mistake of putting the sensor for a clock that shows in and out temp, in a location where I need to get a ladder to retrieve it.  I learned my lesson and have this one handy.  I use lithium batteries as they last much better through the winter in the outside sensor.

Although the up and down indicator is small, it's interesting to note on occasion which way the temperature is headed.  The signal icon shows me I have a good connection to the sensor.  I've never really been aware of the inside humidity before put find the information very useful.  I'm more conscious of how boiling things on the stove, doing laundry or running the dishwasher on a hot day can keep the AC running longer because of the extra humidity inside.  Now I am able to use this information to lower my power bill.  This is a great and handy device that works well.
